Finch '70-30' to play in Australia's World Cup crunch match

SYDNEY : Australia captain Aaron Finch says he is more likely than not to play in Friday's crunch Twenty20 World Cup Super 12 match against Afghanistan, despite suffering a hamstring strain on Tuesday.

The hosts and defending champions probably need to win the Group 1 clash at Adelaide Oval to stay in the tournament and Finch said he would not risk playing if he had any doubts about his fitness.

"(It's) maybe 70-30, but I'll test it out properly this afternoon to make sure that I'm not hindering the side at all ... because I think the worst possible scenario is that you leave the guys short out there with one player fewer."

Tim David also sustained a hamstring issue in the win over Ireland on Tuesday and Finch said the middle order batsman was in the same position as himself.

"He's in exactly the same boat," Finch added. "He'll get worked out today, and we'll know more during training, I guess, the likelihood of both of us playing, one of us, neither of us, whatever it looks like, but exactly the same."

With one more Super 12 match to play, Australia are tied on five points with New Zealand and England at the top of Group 1 but have a far inferior net run rate - the decider for ties in the standings.

Only two teams progress from the group to the semi-finals so Australia need to beat the Afghans and give their net run rate a healthy boost or be reliant on New Zealand or England suffering upsets to get them through.

England take on Sri Lanka on Saturday, while New Zealand face Ireland in Friday's opening game in Adelaide.

The Blacks Caps have by far the best net run rate of the
