Duckworth/Lewis Method of Re-calculating the Target Score in an Interrupted Match. The Professional Edition of the Duckworth/Lewis shall be used in all matches. If any match is suspended after it has started such that the number of overs available to be faced by either side is reduced from that determined when the match started, the revised target shall be computed using the latest version of CODA as distributed by ICC in accordance with the instructions provided with that software and displayed on the screen.

Where possible, arrangements shall be made for the provision of back-up capability, in case of computer malfunction, for the operation or continued operation of the Professional Edition. In the event of computer non-availability or malfunction where no such provision has been made, the Standard Edition (the method in use prior to October 2003) shall be used.

The regulations given below describe only the operation of the Standard Edition, except that Clauses 4, 6 and 7 are also applicable to the Professional Edition.

1. Introduction

The D/L method sets revised targets in rain-interrupted limited-overs matches in accordance with the relative run scoring resources which are at the disposal of the two sides.

These are not in direct proportion to the number of overs available to be faced, as with the average run rate method of correction. Instead they depend on how many overs are to go and how many wickets are down when the interruptions

occur.

To calculate the revised targets, you need to know the resources available at the

stage of the match when suspensions and resumption of play occur. All possible

values of resources have been pre-calculated and these are listed in the

accompanying table.

The table covers each individual ball in a game of up to 50-overs per side. The

figures given in the table are percentages of the resources available for a

complete 50-over innings.

For matches with less than 50-overs per innings before they start, the resource

percentages available at the start of an innings will be less than 100%. But the

same table and the same method of calculation are used whatever the number of

overs per innings.

Page 37

37

The single sheet over-by-over version of the table can be used for cases when

play is suspended before the start of a new over.

When Team 2 (the side batting second) have less run scoring resources at their

disposal than had Team 1 (the side batting first), their target is adjusted

downwards using the ratio of the resources available to the two sides.

But when Team 1’s innings has been interrupted, it often happens than Team 2

have more resources at their disposal than had Team 1 and it is now necessary to

adjust Team 2’s target upwards. In this case the adjustment is based on the runs

that would be expected to be scored on average from the extra resources at their

disposal. The number of these extra runs required is calculated by applying the

excess resource percentage to the average total score in a 50-over innings,

referred to here as G50

For matches involving ICC full member nations, including Under-19

international matches, or for matches between teams that play first class cricket,

the value of G50 to be used at present is 235. For lower levels of the game, G50

should be chosen to represent the average score expected from the team batting first in an uninterrupted 50 overs-per-innings match. For teams between

associate ICC member nations, the recommended value of G50 is 190; for

women’s ODIs, the recommended value is 175. For U15 internationals, the

recommended value is 200. For other levels of the game, advice should be sought

from the ICC.

2. Definitions

• The team batting first are referred to as ‘Team 1’ and the team batting second

are referred to as ‘Team 2’.

• In the table decimal fractions of an over are expressed in standard cricket

notation; i.e. 4.3 overs means 4 overs plus 3 balls.

• The terms ‘target’ and ‘revised target’ are reserved exclusively for the

minimum score Team 2 need to win.

• As with an uninterrupted match, if Team 2 make a score which is one run

short of the target, the match is tied.

The following symbols are used throughout:

N is the number of overs per innings for the match as decided at the moment of

delivery of the first ball of the match.

S is Team 1’s total score.

R1 is the resource percentage (relative to a full 50-over innings) available to

Team 1.

R2 is the resource percentage (relative to a full 50-over innings) available to

Team 2.

T is Team 2’s target score.

Page 38

3. Calculation of the Percentage Resource Lost by a Suspension in Play

To compensate for any loss of overs due to a suspension in play during either

Team 1’s or Team 2’s innings, it is necessary first to calculate the resource

percentage that has been lost on account of this suspension.

If the suspension occurs between overs, use the sheet of the table which gives the

figures for whole numbers of overs. If it occurs mid-over, use the sheets of the

table which provide the figures for each individual ball.

3.1 For the start of the suspension in play, from the table note the resource percentage

that remained for the appropriate number of overs/ball left and wickets lost.

3.2 For the resumption of play after the suspension, from the table note the resource

percentage now remaining for the revised number of overs/balls left and for the

same number of wickets lost.

3.3 Subtract the resource percentage in 3.2 from that in 3.1 to give the resource

percentage lost.

3.4 If a suspension in play causes the innings to be terminated, the resource

percentage on resumption (3.2) is zero and the percentage lost is the resource

percentage which was remaining when the suspension occurred (3.1).

3.5 If more than one suspension in play occurs, the resource percentages lost are

calculated as described in 3.1 to 3.4 and are accumulated to give updated values

for the total resource percentage lost or resource available for the innings. This is

done after each suspension as described in 5.2 and 5.5.

4. Penalties for Slow Over Rates

No overs penalties are imposed for slow over rates and hence slow over rates

have no effect on revised target calculations.

5. Calculation of Revised Targets

5.1 Note the number of overs per innings decided at the start of the game, N. From

the table note the resource percentage available to Team 1 at the start of their innings. (For N = 50 this is 100%.)

5.2 For all suspensions and any premature termination of Team 1’s innings, calculate

the total resource percentage lost using the procedure described in section 3.

Subtract this from the starting resource percentage (5.1) to give R1, the resource

which was available to Team 1 for their innings. Note Team 1’s total score, S.

5.3 There is no overs penalty for slow over rates by either side.

Page 39

39

5.4 Note the number of overs allocated to Team 2 at the start of their innings and

from the table note the resource percentage for this number of overs remaining

and 0 wicket lost. This is R2, the resource percentage available to Team 2. If R2

differs from R1, which will happen if Team 1’s innings was interrupted and/or

Team 2’s was delayed, a revised target must be set. Calculate this revised target,

T, as described in 5.6 below.

5.5 For each suspension of play during Team 2’s innings or for premature

termination of the match, update the resource percentage available, R2, by

subtracting the resource percentage lost calculated as in section 3. Calculate the

revised target, T, after each suspension as described in 5.6 below. If the match

has to be terminated, the result is decided by comparing Team 2’s score at the

time with the ‘par score’, this being the value as calculated in the formulae for T

in 5.6 below, but without the one run added. If it is greater, Team 2 win. If it is

equal, the match is tied. If it is less, Team 1 win.

5.6 If R2 is less than R1, Team 2’s revised target is obtained by reducing Team 1’s

score S in the ratio of R2 to R1, ignoring any figures after the decimal point, and

adding one run

i.e. T = (S x R2/R1) + 1 (rounded down to a whole number, if necessary).

If R2 is equal to R1, no revision is needed and Team 2’s target is one more run

than Team 1’s score.

i.e. T = S + 1

If R2 is greater than R1, calculate the amount of excess resources, R2 – R1, and

take this percentage of the average 50-over total, G50, to give the extra runs

needed, ignoring any figures after the decimal point.

i.e. T = S + (R2 – R1) x G50/100 + 1 (rounded down to a whole number, if

necessary)

6. Penalty Runs

6.1 During Team 1’s innings

If penalty runs are awarded to the batting side, then their score shall advance

accordingly and be taken into account when performing any future D/L

calculation.

If penalty runs are awarded to the fielding side, then any D/L

calculation in between innings will be performed as normal,

and their innings will commence with the score equivalent to

the number of penalty runs that they have been awarded.

6.2 During Team 2’s innings

If penalty runs are awarded to the batting side, then their score shall advance

accordingly. These penalty runs do not affect any subsequent D/L calculation.

Page 40

40

If penalty runs are awarded to the fielding side, then there will be no recalculation

of any D/L target. Instead, the target score and the entire schedule of par scores will advance by the appropriate number of penalty runs. If a loss of overs occurs

after such a penalty has been awarded, then the D/L target will be calculated

based upon the original score of the side batting first, and this target, and all par

scores, will then be raised by the appropriate number of penalty runs

7. The Result and its Description

When a revised target has been calculated and the match has been played out to

its completion, the result is described exactly as in the case of an uninterrupted

match; if Team 2 achieve their revised target they win by the number of wickets

they have in hand when they reach this score; if they fall short of their revised

target by exactly one run the result is a tie, and if they make a lower score Team 1

win by the margin of runs by which Team 2 fall short of the score needed to

achieve a tie.

When a match has to be abandoned with Team 2’s innings in progress (provided

sufficient overs have been bowled to constitute a viable match), the result is

decided by comparing Team 2’s score with the ‘par score’ as defined in 5.5 and

the winning margin is described in terms of the number of runs by which their

score differs from the ‘par score’, regardless of whether Team 1 or Team 2 are

the victors.

Whenever a completed game has involved the use of the D/L method, the

description should be qualified by appending ‘(D/L method)’.

7.1 Examples of result description:

(i) Team 2 are set a revised target of 186. But they only succeed in making 180

in their allocation of overs. They thus fall 5 runs short of the 185 runs

needed to tie the match and the result is described as ‘Team 1 win by 5 runs

(D/L method)’.

(ii) Team 2 are chasing a target of 201 in a 50-over per innings match and reach

105/4 after 25 overs when rain causes the match to be abandoned. At this

point the ‘par score’ is 100. Team 2 have exceeded this by 5 runs and so the

result is described as ‘Team 2 win by 5 runs (D/L method)’.

Example 1 (Suspension during Team 1’s innings)

In a 50 over-per-innings match, Team 1 reaches 79/3 after 20 overs and then

there is a suspension in play. It is decided that 20 overs of the match should be

Page 41

41

lost, 10 of these by each team. Team 1 resumes to reach a final total of 180 in its

revised allocation of 40 overs.

Number of overs per innings at the start of match, N = 50

Resource percentage available to Team 1 at start of innings = 100% (5.1)

Resource percentage remaining at suspension (30 overs left, 3 wkts lost = 61.6%

(3.1)

Resource percentage remaining at resumption (20 overs left, 3 wkts lost) = 49.1%

(3.2)

Resource percentage lost due to suspension = 61.6 – 49.1 = 12.5% (3.3)

Resource percentage available to Team 1, R1 = 100 – 12.5 = 87.5% (5.2)

Number of overs available to Team 2 at the start of its innings = 40

Resource percentage available (40 overs left, 0 wkt lost), R2 = 89.3% (5.4)

R2 is greater than R1, i.e. Team 2 has more resource available than had Team 1,

so its target should be increased. S = 180

Team 2’s revised target (5.6) is

T = S + G50 x (R2 – R1)/100 + 1 = 180 + 235 x (89.3 – 87.5)/100 + 1 = 185

(rounded down).

Example 2 (delay to start of Team 2’s innings)

In an English National League match (45 overs per innings), Team 1 scores 212

in its allocated 45 overs. Rain then causes Team 2’s response to be delayed and it

is decided that it should be shortened to 35 overs.

Number of overs at start of match, N = 45.

Resource percentage available to Team 1 at start of its innings (45 overs left, 0

wkt lost) = 95.0% (5.1).

The innings was not interrupted, so R1 = 95.0%

Number of overs available to Team 2 at start of its innings = 35

Resource percentage available to Team 2 at start of innings (35 overs left, 0 wkt

lost) R2 = 82.7% (5.4)

R2 is less than R1; S = 212

Team 2’s revised target (5.6) is

Page 42

42

T = S x R2/R1 + 1 = 212 x 82.7/95.0 + 1 = 185 (rounded down).

Example 3 (suspension during Team 2’s innings)

In an One Day International match (50 overs per innings), Team 1 has scored 250

from its allocation of 50 overs in an uninterrupted innings. Team 2 has received

12 overs and has scored 40/1. Then play is suspended and 10 overs are lost.

Number of overs at start of match, N = 50.

Team 1’s innings was uninterrupted, so its resource percentage available, R1 =

100% (5.1).

Resource percentage available to Team 2 at start of innings = 100% (5.4).

Resource percentage remaining at suspension (38 overs left, 1 wkt lost) = 82.0%

(3.1).

Resource percentage remaining at resumption (28 overs left, 1 wkt lost) = 68.8%

(3.2).

Resource percentage lost due to suspension = 82.0 – 68.8 = 13.2% (3.3).

Resource percentage available to Team 2, R2 = 100 – 13.2 = 86.8% (5.5).

R2 is less than R1; S = 250.

Team 2’s revised target (5.6) is

T = S x R2/R1 + 1 = 250 x 86.8/100 + 1 = 218 , and it needs a further 178 runs

from 28 overs.

Example 4 (multiple suspensions and abandonment)

Suppose that in Example 3, play continues for a further 10 overs during which

Team 2 takes its score on to 98/3, whereupon there is another suspension in play

and 2 more overs are lost. A further 8.2 overs are bowled and Team 2 is 154/6

when rain washes out the match.

Team 1’s resource percentage is still R1 = 100%.

Team 2’s resource percentage has been reduced further.

Resource percentage remaining at start of second suspension (18 overs left, 3

wkts lost) = 45.9% (3.1).

Page 43

43

Resource percentage remaining at end of second suspension (16 overs left, 3 wkts

lost) = 42.3% (3.2).

Resource percentage lost due to second suspension = 45.9 – 42.3 = 3.6% (3.3).

Resource percentage available to Team 2, R2 = 86.8 – 3.6 = 83.2% (5.5).

R2 is less than R1; S = 250.

Team 2’s revised target (5.6) is T = S x R2/R1 + 1 = 250 x 83.2/100 + 1 = 209 and it needs a further 111 runs

from 16 overs.

When the innings had to be terminated, there were 7.4 overs remaining.

Resource percentage remaining at termination of Team 2’s innings (7.4 overs left,

6 wkts lost) = 19.4%.

This remaining resource is lost by the termination.

Resource percentage available to Team 2, R2 = 83.2 – 19.4 = 63.8% (5.5).

R2 is less than R1; S = 250.

Team 2’s par score (5.5 and 5.6) is S x R2/R1 = 250 x 63.8/100 = 159 (rounded

down); the par score at the instant of abandonment is 159 and with a score of 154

it has lost by 5 runs.

Team 1 wins by 5 runs (D/L method) (7).

Example 5 (suspension and termination of Team 1’s innings mid-over and delay

to Team 2’s innings)

This is taken form an actual ODI: India (Team 1) versus Pakistan (Team 2),

Singapore, April 1996. Team 1 scores 226/8 in 47.1 of a scheduled 50 overs.

Rain then terminates Team 1’s innings and delays that of Team 2, which is given

a reduced allocation of 33 overs.

Number of overs per innings at start of match, N = 50

Team 1’s innings:

Resource percentage at start of innings is 100% (5.1).

Resource percentage remaining at termination (2.5 overs left, 8 wkts lost) = 6.9%

(3.1).

Resource percentage lost due to termination = 6.9% (3.4).

Resource percentage available, R1 = 100 – 8.1 = 93.1% (5.2).

Page 44

44

Team 2’s innings (allocated 33 overs):

Resource percentage available at star to f innings (33 overs left, 0 wkts lost), R2

= 79.8% (5.4).

R2 is less than R1; S = 226.

Team 2’s revised target (5.6) is

T = S x R2/R1 + 1 = 226 x 79.8/93.1 + 1 = 194 (rounded down).

Example 6 (as Example 5 but with a further interruption during Team 2’s

innings)

In the match of the previous example, Team 2 has scored 140 for 2 after 25 overs

when a further 5 overs are lost to the weather.

Team 1’s resource percentage is still R1 = 93.1%.

Team 2’s innings:

Resource percentage at start of innings (33 overs left, 0 wkt lost) = 79.8% (5.4).

Resource percentage remaining at suspension (8 overs left, 2 wkts lost) = 25.5%

(3.1).

Resource percentage remaining at resumption (3 overs left, 2 wkts lost) = 10.4 %

(3.2).

Resource percentage lost due to suspension = 25.5 – 10.4 = 15.1% (3.3).

Resource percentage available, R2 = 79.8 – 15.1 = 64.7% (5.2).

R2 is less than R1; S = 226.

Team 2’s revised target (5.6) is

T = S x R2/R1 + 1 = 226 x 64.7/93.1 + 1 = 158 (rounded down) and it needs a

further 18 runs from 3 overs.

APPENDIX G

WCL Div 1 2007 - Procedure for the Bowl Out in the Final

The following procedure will apply should the provision for a bowl out be adopted in

any match.

1. Subject to weather conditions the bowl out will take place on the scheduled day of

the match at a time to be determined by the tournament referee.

2. The bowl out will take place on the pitch allocated for the match (the designated

pitch) unless otherwise determined by the umpires in consultation with the ground

authority and the tournament referee.

3. A full set of stumps, including bails, will be pitched at both ends of the designated

pitch.

4. The bowlers will all bowl from the same end.

5. The tournament referee shall decide which end the bowlers will bowl from.

6. ICC shall ensure there is an adequate supply of dry, used balls.

7. The captains shall toss a coin for the right to decide which team bowls first or

second in the bowl out. The tournament referee will supervise the toss in the

normal manner.

8. The captains shall nominate their five bowlers to each other, the umpires and

referee prior to the toss. In the event of injury during the bowl out, the injured

player may be replaced by another bowler.

9. The wicket keeper will not be permitted to stand up to the stumps.

10. No bowler will be allowed a practice delivery.

11. The umpires will stand in their normal positions and will be responsible for

officially recording the number of ‘hits’ on the wicket. Their decision shall be

final as to the result.

12. The referee will be responsible for making sure only the chosen bowlers actually

bowl, and that no bowler bowls more than once until permitted to do so.

13. The bowls are taken alternately by the teams.

14. The team with the most number of hits after five bowls shall be declared the

winner.

Page 52

52

15. If, after both teams have taken five bowls, both have scored the same number of

hits on the wicket, or have not scored any hits, bowls continue to be taken in the

same order until one team has scored a hit more than the other from the same

number of bowls. That team shall be declared the winner.

16. Each bowl is taken by a different player and all 10 eligible players (the wicket

keeper shall not bowl) must bowl a delivery before any player can take a second

bowl.

17. Only the eligible players and match officials are permitted to remain on the field of play when the bowls are being taken.

18. All players, except the bowler at the time and the wicket keeper, must remain just outside the 30 yard circle at mid-wicket.

19. Unless otherwise stated by the referee and on-field umpires, Law 24 and ICC

standard playing condition 24.1 shall apply. In the case of an infringement the

umpire shall call ‘no ball’ and the delivery shall be considered a miss and will not

be retaken.

1. Introduction

The D/L method sets revised targets in rain-interrupted limited-overs matches in accordance with the relative run scoring resources which are at the disposal of the two sides.

These are not in direct proportion to the number of overs available to be faced, as with the average run rate method of correction. Instead they depend on how many overs are to go and how many wickets are down when the interruptions

occur.

To calculate the revised targets, you need to know the resources available at the

stage of the match when suspensions and resumption of play occur. All possible

values of resources have been pre-calculated and these are listed in the

accompanying table.

The table covers each individual ball in a game of up to 50-overs per side. The

figures given in the table are percentages of the resources available for a

complete 50-over innings.

For matches with less than 50-overs per innings before they start, the resource

percentages available at the start of an innings will be less than 100%. But the

same table and the same method of calculation are used whatever the number of

overs per innings.

Page 37

37

The single sheet over-by-over version of the table can be used for cases when

play is suspended before the start of a new over.

When Team 2 (the side batting second) have less run scoring resources at their

disposal than had Team 1 (the side batting first), their target is adjusted

downwards using the ratio of the resources available to the two sides.

But when Team 1’s innings has been interrupted, it often happens than Team 2

have more resources at their disposal than had Team 1 and it is now necessary to

adjust Team 2’s target upwards. In this case the adjustment is based on the runs

that would be expected to be scored on average from the extra resources at their

disposal. The number of these extra runs required is calculated by applying the

excess resource percentage to the average total score in a 50-over innings,

referred to here as G50

For matches involving ICC full member nations, including Under-19

international matches, or for matches between teams that play first class cricket,

the value of G50 to be used at present is 235. For lower levels of the game, G50

should be chosen to represent the average score expected from the team batting first in an uninterrupted 50 overs-per-innings match. For teams between

associate ICC member nations, the recommended value of G50 is 190; for

women’s ODIs, the recommended value is 175. For U15 internationals, the

recommended value is 200. For other levels of the game, advice should be sought

from the ICC.

2. Definitions

• The team batting first are referred to as ‘Team 1’ and the team batting second

are referred to as ‘Team 2’.

• In the table decimal fractions of an over are expressed in standard cricket

notation; i.e. 4.3 overs means 4 overs plus 3 balls.

• The terms ‘target’ and ‘revised target’ are reserved exclusively for the

minimum score Team 2 need to win.

• As with an uninterrupted match, if Team 2 make a score which is one run

short of the target, the match is tied.

The following symbols are used throughout:

N is the number of overs per innings for the match as decided at the moment of

delivery of the first ball of the match.

S is Team 1’s total score.

R1 is the resource percentage (relative to a full 50-over innings) available to

Team 1.

R2 is the resource percentage (relative to a full 50-over innings) available to

Team 2.

T is Team 2’s target score.

Page 38

3. Calculation of the Percentage Resource Lost by a Suspension in Play

To compensate for any loss of overs due to a suspension in play during either

Team 1’s or Team 2’s innings, it is necessary first to calculate the resource

percentage that has been lost on account of this suspension.

If the suspension occurs between overs, use the sheet of the table which gives the

figures for whole numbers of overs. If it occurs mid-over, use the sheets of the

table which provide the figures for each individual ball.

3.1 For the start of the suspension in play, from the table note the resource percentage

that remained for the appropriate number of overs/ball left and wickets lost.

3.2 For the resumption of play after the suspension, from the table note the resource

percentage now remaining for the revised number of overs/balls left and for the

same number of wickets lost.

3.3 Subtract the resource percentage in 3.2 from that in 3.1 to give the resource

percentage lost.

3.4 If a suspension in play causes the innings to be terminated, the resource

percentage on resumption (3.2) is zero and the percentage lost is the resource

percentage which was remaining when the suspension occurred (3.1).

3.5 If more than one suspension in play occurs, the resource percentages lost are

calculated as described in 3.1 to 3.4 and are accumulated to give updated values

for the total resource percentage lost or resource available for the innings. This is

done after each suspension as described in 5.2 and 5.5.

4. Penalties for Slow Over Rates

No overs penalties are imposed for slow over rates and hence slow over rates

have no effect on revised target calculations.

5. Calculation of Revised Targets

5.1 Note the number of overs per innings decided at the start of the game, N. From

the table note the resource percentage available to Team 1 at the start of their innings. (For N = 50 this is 100%.)

5.2 For all suspensions and any premature termination of Team 1’s innings, calculate

the total resource percentage lost using the procedure described in section 3.

Subtract this from the starting resource percentage (5.1) to give R1, the resource

which was available to Team 1 for their innings. Note Team 1’s total score, S.

5.3 There is no overs penalty for slow over rates by either side.

Page 39

39

5.4 Note the number of overs allocated to Team 2 at the start of their innings and

from the table note the resource percentage for this number of overs remaining

and 0 wicket lost. This is R2, the resource percentage available to Team 2. If R2

differs from R1, which will happen if Team 1’s innings was interrupted and/or

Team 2’s was delayed, a revised target must be set. Calculate this revised target,

T, as described in 5.6 below.

5.5 For each suspension of play during Team 2’s innings or for premature

termination of the match, update the resource percentage available, R2, by

subtracting the resource percentage lost calculated as in section 3. Calculate the

revised target, T, after each suspension as described in 5.6 below. If the match

has to be terminated, the result is decided by comparing Team 2’s score at the

time with the ‘par score’, this being the value as calculated in the formulae for T

in 5.6 below, but without the one run added. If it is greater, Team 2 win. If it is

equal, the match is tied. If it is less, Team 1 win.

5.6 If R2 is less than R1, Team 2’s revised target is obtained by reducing Team 1’s

score S in the ratio of R2 to R1, ignoring any figures after the decimal point, and

adding one run

i.e. T = (S x R2/R1) + 1 (rounded down to a whole number, if necessary).

If R2 is equal to R1, no revision is needed and Team 2’s target is one more run

than Team 1’s score.

i.e. T = S + 1

If R2 is greater than R1, calculate the amount of excess resources, R2 – R1, and

take this percentage of the average 50-over total, G50, to give the extra runs

needed, ignoring any figures after the decimal point.

i.e. T = S + (R2 – R1) x G50/100 + 1 (rounded down to a whole number, if

necessary)

6. Penalty Runs

6.1 During Team 1’s innings

If penalty runs are awarded to the batting side, then their score shall advance

accordingly and be taken into account when performing any future D/L

calculation.

If penalty runs are awarded to the fielding side, then any D/L

calculation in between innings will be performed as normal,

and their innings will commence with the score equivalent to

the number of penalty runs that they have been awarded.

6.2 During Team 2’s innings

If penalty runs are awarded to the batting side, then their score shall advance

accordingly. These penalty runs do not affect any subsequent D/L calculation.

Page 40

40

If penalty runs are awarded to the fielding side, then there will be no recalculation

of any D/L target. Instead, the target score and the entire schedule of par scores will advance by the appropriate number of penalty runs. If a loss of overs occurs

after such a penalty has been awarded, then the D/L target will be calculated

based upon the original score of the side batting first, and this target, and all par

scores, will then be raised by the appropriate number of penalty runs

7. The Result and its Description

When a revised target has been calculated and the match has been played out to

its completion, the result is described exactly as in the case of an uninterrupted

match; if Team 2 achieve their revised target they win by the number of wickets

they have in hand when they reach this score; if they fall short of their revised

target by exactly one run the result is a tie, and if they make a lower score Team 1

win by the margin of runs by which Team 2 fall short of the score needed to

achieve a tie.

When a match has to be abandoned with Team 2’s innings in progress (provided

sufficient overs have been bowled to constitute a viable match), the result is

decided by comparing Team 2’s score with the ‘par score’ as defined in 5.5 and

the winning margin is described in terms of the number of runs by which their

score differs from the ‘par score’, regardless of whether Team 1 or Team 2 are

the victors.

Whenever a completed game has involved the use of the D/L method, the

description should be qualified by appending ‘(D/L method)’.

7.1 Examples of result description:

(i) Team 2 are set a revised target of 186. But they only succeed in making 180

in their allocation of overs. They thus fall 5 runs short of the 185 runs

needed to tie the match and the result is described as ‘Team 1 win by 5 runs

(D/L method)’.

(ii) Team 2 are chasing a target of 201 in a 50-over per innings match and reach

105/4 after 25 overs when rain causes the match to be abandoned. At this

point the ‘par score’ is 100. Team 2 have exceeded this by 5 runs and so the

result is described as ‘Team 2 win by 5 runs (D/L method)’.

Example 1 (Suspension during Team 1’s innings)

In a 50 over-per-innings match, Team 1 reaches 79/3 after 20 overs and then

there is a suspension in play. It is decided that 20 overs of the match should be

Page 41

41

lost, 10 of these by each team. Team 1 resumes to reach a final total of 180 in its

revised allocation of 40 overs.

Number of overs per innings at the start of match, N = 50

Resource percentage available to Team 1 at start of innings = 100% (5.1)

Resource percentage remaining at suspension (30 overs left, 3 wkts lost = 61.6%

(3.1)

Resource percentage remaining at resumption (20 overs left, 3 wkts lost) = 49.1%

(3.2)

Resource percentage lost due to suspension = 61.6 – 49.1 = 12.5% (3.3)

Resource percentage available to Team 1, R1 = 100 – 12.5 = 87.5% (5.2)

Number of overs available to Team 2 at the start of its innings = 40

Resource percentage available (40 overs left, 0 wkt lost), R2 = 89.3% (5.4)

R2 is greater than R1, i.e. Team 2 has more resource available than had Team 1,

so its target should be increased. S = 180

Team 2’s revised target (5.6) is

T = S + G50 x (R2 – R1)/100 + 1 = 180 + 235 x (89.3 – 87.5)/100 + 1 = 185

(rounded down).

Example 2 (delay to start of Team 2’s innings)

In an English National League match (45 overs per innings), Team 1 scores 212

in its allocated 45 overs. Rain then causes Team 2’s response to be delayed and it

is decided that it should be shortened to 35 overs.

Number of overs at start of match, N = 45.

Resource percentage available to Team 1 at start of its innings (45 overs left, 0

wkt lost) = 95.0% (5.1).

The innings was not interrupted, so R1 = 95.0%

Number of overs available to Team 2 at start of its innings = 35

Resource percentage available to Team 2 at start of innings (35 overs left, 0 wkt

lost) R2 = 82.7% (5.4)

R2 is less than R1; S = 212

Team 2’s revised target (5.6) is

Page 42

42

T = S x R2/R1 + 1 = 212 x 82.7/95.0 + 1 = 185 (rounded down).

Example 3 (suspension during Team 2’s innings)

In an One Day International match (50 overs per innings), Team 1 has scored 250

from its allocation of 50 overs in an uninterrupted innings. Team 2 has received

12 overs and has scored 40/1. Then play is suspended and 10 overs are lost.

Number of overs at start of match, N = 50.

Team 1’s innings was uninterrupted, so its resource percentage available, R1 =

100% (5.1).

Resource percentage available to Team 2 at start of innings = 100% (5.4).

Resource percentage remaining at suspension (38 overs left, 1 wkt lost) = 82.0%

(3.1).

Resource percentage remaining at resumption (28 overs left, 1 wkt lost) = 68.8%

(3.2).

Resource percentage lost due to suspension = 82.0 – 68.8 = 13.2% (3.3).

Resource percentage available to Team 2, R2 = 100 – 13.2 = 86.8% (5.5).

R2 is less than R1; S = 250.

Team 2’s revised target (5.6) is

T = S x R2/R1 + 1 = 250 x 86.8/100 + 1 = 218 , and it needs a further 178 runs

from 28 overs.

Example 4 (multiple suspensions and abandonment)

Suppose that in Example 3, play continues for a further 10 overs during which

Team 2 takes its score on to 98/3, whereupon there is another suspension in play

and 2 more overs are lost. A further 8.2 overs are bowled and Team 2 is 154/6

when rain washes out the match.

Team 1’s resource percentage is still R1 = 100%.

Team 2’s resource percentage has been reduced further.

Resource percentage remaining at start of second suspension (18 overs left, 3

wkts lost) = 45.9% (3.1).

Page 43

43

Resource percentage remaining at end of second suspension (16 overs left, 3 wkts

lost) = 42.3% (3.2).

Resource percentage lost due to second suspension = 45.9 – 42.3 = 3.6% (3.3).

Resource percentage available to Team 2, R2 = 86.8 – 3.6 = 83.2% (5.5).

R2 is less than R1; S = 250.

Team 2’s revised target (5.6) is T = S x R2/R1 + 1 = 250 x 83.2/100 + 1 = 209 and it needs a further 111 runs

from 16 overs.

When the innings had to be terminated, there were 7.4 overs remaining.

Resource percentage remaining at termination of Team 2’s innings (7.4 overs left,

6 wkts lost) = 19.4%.

This remaining resource is lost by the termination.

Resource percentage available to Team 2, R2 = 83.2 – 19.4 = 63.8% (5.5).

R2 is less than R1; S = 250.

Team 2’s par score (5.5 and 5.6) is S x R2/R1 = 250 x 63.8/100 = 159 (rounded

down); the par score at the instant of abandonment is 159 and with a score of 154

it has lost by 5 runs.

Team 1 wins by 5 runs (D/L method) (7).

Example 5 (suspension and termination of Team 1’s innings mid-over and delay

to Team 2’s innings)

This is taken form an actual ODI: India (Team 1) versus Pakistan (Team 2),

Singapore, April 1996. Team 1 scores 226/8 in 47.1 of a scheduled 50 overs.

Rain then terminates Team 1’s innings and delays that of Team 2, which is given

a reduced allocation of 33 overs.

Number of overs per innings at start of match, N = 50

Team 1’s innings:

Resource percentage at start of innings is 100% (5.1).

Resource percentage remaining at termination (2.5 overs left, 8 wkts lost) = 6.9%

(3.1).

Resource percentage lost due to termination = 6.9% (3.4).

Resource percentage available, R1 = 100 – 8.1 = 93.1% (5.2).

Page 44

44

Team 2’s innings (allocated 33 overs):

Resource percentage available at star to f innings (33 overs left, 0 wkts lost), R2

= 79.8% (5.4).

R2 is less than R1; S = 226.

Team 2’s revised target (5.6) is

T = S x R2/R1 + 1 = 226 x 79.8/93.1 + 1 = 194 (rounded down).

Example 6 (as Example 5 but with a further interruption during Team 2’s

innings)

In the match of the previous example, Team 2 has scored 140 for 2 after 25 overs

when a further 5 overs are lost to the weather.

Team 1’s resource percentage is still R1 = 93.1%.

Team 2’s innings:

Resource percentage at start of innings (33 overs left, 0 wkt lost) = 79.8% (5.4).

Resource percentage remaining at suspension (8 overs left, 2 wkts lost) = 25.5%

(3.1).

Resource percentage remaining at resumption (3 overs left, 2 wkts lost) = 10.4 %

(3.2).

Resource percentage lost due to suspension = 25.5 – 10.4 = 15.1% (3.3).

Resource percentage available, R2 = 79.8 – 15.1 = 64.7% (5.2).

R2 is less than R1; S = 226.

Team 2’s revised target (5.6) is

T = S x R2/R1 + 1 = 226 x 64.7/93.1 + 1 = 158 (rounded down) and it needs a

further 18 runs from 3 overs.

APPENDIX G

WCL Div 1 2007 - Procedure for the Bowl Out in the Final

The following procedure will apply should the provision for a bowl out be adopted in

any match.

1. Subject to weather conditions the bowl out will take place on the scheduled day of

the match at a time to be determined by the tournament referee.

2. The bowl out will take place on the pitch allocated for the match (the designated

pitch) unless otherwise determined by the umpires in consultation with the ground

authority and the tournament referee.

3. A full set of stumps, including bails, will be pitched at both ends of the designated

pitch.

4. The bowlers will all bowl from the same end.

5. The tournament referee shall decide which end the bowlers will bowl from.

6. ICC shall ensure there is an adequate supply of dry, used balls.

7. The captains shall toss a coin for the right to decide which team bowls first or

second in the bowl out. The tournament referee will supervise the toss in the

normal manner.

8. The captains shall nominate their five bowlers to each other, the umpires and

referee prior to the toss. In the event of injury during the bowl out, the injured

player may be replaced by another bowler.

9. The wicket keeper will not be permitted to stand up to the stumps.

10. No bowler will be allowed a practice delivery.

11. The umpires will stand in their normal positions and will be responsible for

officially recording the number of ‘hits’ on the wicket. Their decision shall be

final as to the result.

12. The referee will be responsible for making sure only the chosen bowlers actually

bowl, and that no bowler bowls more than once until permitted to do so.

13. The bowls are taken alternately by the teams.

14. The team with the most number of hits after five bowls shall be declared the

winner.

Page 52

52

15. If, after both teams have taken five bowls, both have scored the same number of

hits on the wicket, or have not scored any hits, bowls continue to be taken in the

same order until one team has scored a hit more than the other from the same

number of bowls. That team shall be declared the winner.

16. Each bowl is taken by a different player and all 10 eligible players (the wicket

keeper shall not bowl) must bowl a delivery before any player can take a second

bowl.

17. Only the eligible players and match officials are permitted to remain on the field of play when the bowls are being taken.

18. All players, except the bowler at the time and the wicket keeper, must remain just outside the 30 yard circle at mid-wicket.

19. Unless otherwise stated by the referee and on-field umpires, Law 24 and ICC

standard playing condition 24.1 shall apply. In the case of an infringement the

umpire shall call ‘no ball’ and the delivery shall be considered a miss and will not

be retaken.
