Who needs what to progress in T20 World Cup?

The Super 12 stage of the Men’s T20 World Cup is set for a thrilling climax with all to play for as we enter the final round of matches.

With a number of teams likely to end level on points, net run-rate could decide who progresses and who is getting the next flight home.

But what are the permutations? And how do you calculate net run-rate?

BBC Sport has been crunching the numbers to find out…

Group 1

Remaining fixtures (all times GMT): Saturday, 5 Nov: Sri Lanka v England (08:00).

New Zealand have qualified for the semi-finals following their 35-run win over Ireland on Friday. The Kiwis have not officially secured top spot in the group but barring an England win over Sri Lanka by an enormous margin, they will go through as group winners.

Australia moved into the top two with a nervy four-run win over Afghanistan on Friday. They need Sri Lanka to beat England if they are to make it through to the last four. Any England win will knock the hosts out of the competition.

England know a win over Sri Lanka would guarantee their progress into the semi-finals because their net run-rate is significantly better than Australia’s. Theoretically, Jos Buttler’s side could top the group but that would require a victory of 128 runs or more against Sri Lanka.

Sri Lanka, Ireland and Afghanistan can no longer qualify. Sri Lanka will finish no lower than fourth, Ireland and Afghanistan are confirmed as finishing fifth and sixth, respectively.

Group 2

Remaining fixtures (all times GMT): Sunday, 6 Nov: South Africa v Netherlands (00:00), Pakistan v Bangladesh (04:00), Zimbabwe v India (08:00).

India will progress with a victory over Zimbabwe. They will also go through if the game is washed out as only South Africa can match a seven-point tally.

South Africa need to beat the Netherlands in their final game.

Bangladesh must beat Pakistan in their final game and hope India lose to Zimbabwe, though they could still miss out unless they improve their net run-rate.

Pakistan can also still progress but need to beat Bangladesh and hope that South Africa lose to the Netherlands, or the game is washed out.

Zimbabwe are all but out. They need the Netherlands to beat South Africa, Pakistan-Bangladesh to be washed out and to beat India. Even then they would also need to vastly improve their net run-rate.

Netherlands can no longer qualify.

How is net run-rate calculated?

Run-rate is the average number of runs scored per over by a team in their entire innings – so, for example, a score of 160 off 20 overs equals eight runs per over.

Net run-rate is calculated by subtracting the opposition’s run-rate from the other team’s run-rate.

The winning side will therefore have a positive net run-rate, and the losers a negative net run-rate.

In a tournament, net run-rate is worked out by taking the average runs per over scored by that team in each game and subtracting the average runs per over scored against them in each game.

If a team is bowled out inside their allotted overs, their run-rate is calculated by dividing the runs by the maximum overs they could have batted – 20 overs in the case of this tournament.
