Group 1 scenarios: Australia frontrunners for second spot

Australia's stunning victory against Bangladesh, with 82 balls to spare, has completely turned around the net-run-rate story in Group 1. With West Indies knocked out, it is now a straight race between Australia and South Africa for the second semi-final spot. Here is a look at what they need to do in their final games to qualify.

From -0.627, Australia's net run rate has jumped up to 1.031, thanks to their ridiculously one-sided win against Bangladesh. This means they are now the frontrunners to take the second spot in the group: South Africa, who are also on six points, have an NRR of 0.742 and have table-toppers England to negotiate in their last match, while Australia take on West Indies, which should surely be an easier proposition.

Australia will be through if they beat West Indies and if England beat South Africa. If Australia lose their last game and South Africa win theirs, then South Africa will qualify as the second team.

If both Australia and South Africa lose and remain on six points, then the defeat margins will determine which team ends up with a higher NRR: if Australia, chasing 161, lose by 20 runs, then South Africa can lose by no more than three runs (chasing 161) to be ahead of Australia on run rate. If Australia score 160 and win by 10 runs, South Africa will have to win by at least 32 runs (with the same score) to finish with a better NRR than Australia. Since South Africa play the second game on Saturday, they will know what they need to do to qualify.

While Australia's NRR has improved significantly, England still remain firm favourites to top the group. Even if Australia beat West Indies by 100 runs, they will need England to lose by around 43 runs to top the group.
