Afghanistan kept its Twenty20 World Cup semifinal hopes alive by stunning previously unbeaten Australia by 21 runs in a thrilling encounter at St. Vincent later on Saturday.

Despite a second successive hat-trick by Australian bowler Pat Cummins, Afghanistan posted 148-6 after being asked to bat first on a tricky pitch at the Arnos Vale Ground.

Afghanistan pair Rahmanullah Gurbaz and Ibrahim Zadran put on 118 for the highest opening partnership against Australia in a T20 match before Australia’s bowlers rallied late, including Cummins’ second career hat-trick — just two days after his first.

Australia then stumbled with the bat and were all out for 127, with only Glenn Maxwell (59 off 41 balls) coming to grips with the superb Afghanistan bowling attack and the deteriorating wicket.

Man of the match Guldabin Naib took four wickets in an inspired spell in the middle overs to stall Australia’s chase before Azmatullah Omarzai had final wicket Adam Zampa caught in the deep in the final over to complete a stunning win amid jubilant celebrations among the Afghan players and team management.

The victory moves Afghanistan to two points in Group 1 and level with Australia, but behind on net run rate. India leads the group on four points, with Bangladesh bottom on zero points but still with a chance of qualifying for the semifinals.

The final group standings will be decided on Monday when Afghanistan plays Bangladesh at St. Vincent and Australia play India Monday at St. Lucia.
