What do England need to reach T20 World Cup semi-finals?

England's hopes of reaching the T20 World Cup semi-finals are in the balance after suffering a narrow seven-run defeat to South Africa in Saint Lucia.

Jos Buttler's side made the perfect start to the Super 8s with an excellent eight-wicket win over co-hosts West Indies, but their loss to the Proteas means there is still work to be done if they are to reach the last four.

BBC Sport looks at the current state of play in Group 2 and what England need to do to qualify.

Saturday, 22 June (01:30 BST): USA v West Indies (Sat 01:30 BST)

Sunday, 23 June (15:30 BST): USA v England (Sun 15:30 BST)

Monday, 24 June (01:30 BST): West Indies v South Africa

In short, yes.

If England beat USA on Sunday then they have a very good chance of reaching the semi-finals.

It could go down to net run-rate again though, if West Indies beat USA and South Africa in their remaining games.

They could also progress on net run-rate with a defeat, though they would need West Indies to beat USA and then lose to South Africa.

That would see South Africa top the group with six points and England, West Indies and USA all on two points.

Run-rate is the average number of runs scored per over by a team in their entire innings - so, for example, a score of 140 off 20 overs equals seven 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.
