Points System:Win → 2 pointsNo Result → 1 point
In a tied match, the winner will be determined by:a. Team losing fewer wicketsb. If equal: Most runs in last 10 overs → then last 5 overs → then last 1 over
Lions 150/6, Tigers 150/6: the scores are level, so the tie-break runs in order.
Matches must start on time (except Finals Day).• Each innings must be completed within 85 minutes.
Any team not completing their overs in the allotted time will incur a 5-run penalty per full over not completed.
Standard match length: 20 overs per side.
Teams cannot mutually agree to shorten a match unless approved by OPL organizers.
If the start is delayed in the first innings (weather, ground, or injury):• 1 over deducted per side for every full 7 minutes lost.
In the second innings:• 1 over deducted for every full 3.5 minutes lost.
Minimum overs required for a result: 10 overs per side, unless a result is already achieved.
Target score will be recalculated by the official scoring app (minimum 10-over rule applies). How it is worked out
One over a side comes off for every full 7 minutes lost: 2 off.
The umpires decide how many overs each side will now get. If the two sides end up with different chances to score, the target for the side batting second is recalculated so the contest stays fair. The scoring console does the arithmetic; the umpires' announced figure is always the one that stands.
The Duckworth/Lewis method, Standard Edition: the published, table-based version of the rain rule. It is the version the playing conditions fall back on whenever the licensed D/L/S computer program isn't available, which is every club and community match.
International matches use that licensed program (the “Professional Edition”, now called D/L/S). It follows the same idea and usually gives the same or a very close target; it can differ by a few runs after very high first-innings scores.
A batting side has two things to score runs with: overs still to be bowled and wickets still in hand. The method puts the two together as one percentage of a full 50-over innings. Losing overs matters less when you have already lost wickets, and more when you have plenty in hand.
| Overs left | 0 down | 2 down | 5 down | 8 down |
|---|---|---|---|---|
| 20 | 56.6% | 52.4% | 38.6% | 11.9% |
| 15 | 45.2% | 42.6% | 33.5% | 11.8% |
| 10 | 32.1% | 30.8% | 26.1% | 11.4% |
| 5 | 17.2% | 16.8% | 15.4% | 9.4% |
| 2 | 7.2% | 7.1% | 6.8% | 5.5% |
A few rows of the full table (50 overs down to 0, for 0 to 9 wickets lost). A 20-over innings starts with 56.6% because 20 overs with all ten wickets is that much of a 50-over innings.
Call the first side's total S, the resources it had R1, and the resources the chasing side has R2.
One run short of the target is a tie.
Example 1: the chase is shortened before it starts
Lions make 142 in their 20 overs. It rains at the break and Tigers will get 12 overs.
Tigers need 95 from 12 overs.
Example 2: rain during the chase
Chasing 143 in 20 overs, Tigers have lost 2 wickets after 8 overs when rain takes 4 overs away. They will now get 16.
The target comes down from 143 to 117. What Tigers have already scored still counts.
Example 3: rain in the first innings (the target goes up)
Lions have lost 2 wickets after 10 of their 20 overs when rain cuts the match to 15 overs a side. They finish on 110.
Tigers need 116, not 111. Lions batted the first 10 overs as if they had 20, saving wickets they never got to use; Tigers can plan for 15 from the start.
Example 4: the match can't be finished
Chasing 143 in 20 overs, Tigers are 88/3 after 12 overs when the match is abandoned.
Tigers are 9 ahead of par: Tigers win by 9 runs (DLS method).
Yes. Under the Match Rules above, each side must have had the chance to bat 10 overs for a result, unless one has already been reached. Short of that, the match is a no result and the points are shared. The console will work out a par score at any point, so it is the umpires who apply the minimum.
Because the side batting first was interrupted without warning. It paced its innings for the full overs, then lost the overs in which sides score fastest. The chasing side knows its overs from the first ball and can attack throughout, so it is asked for a few more runs. Example 3 shows it.
G50 is the total an average side would make batting first in a full 50-over innings. It is only used when the chasing side has more resources than the first side (the second formula). The published guidance gives 245 for first-class cricket and recommends 200 for lower levels of the game, which is what OPL uses.
The table is published over by over and ball by ball. The console holds the over-by-over figures and, for a break in mid-over, takes the value in proportion between the two overs either side. That can differ from the ball-by-ball sheet by a tenth of a percent, which very occasionally means one run. Where it matters, restart from the end of an over or use the umpires' figure.
Yes. In the console, Rain: overs / target shows the working and fills in the target; the scorer can type the umpires' figure over it before applying. Penalty runs awarded later simply move the score, not the target.
