Fast bowler Pat Cummins took a hat-trick and David Warner smashed an unbeaten half-century as undefeated Australia kicked off their Super Eight campaign at the T20 World Cup with a rain-hit 28-run win over Bangladesh on Thursday. Recalled with fellow quick Josh Hazlewood after being rested against Scotland, Cummins’s three-wicket burst helped restrict the South Asians to 140 for eight before rain cut short Australia’s chase. Victory was secured by the Duckworth-Lewis method. Australia were 100 for two after 11.2 overs before the match was abandoned, with Warner unbeaten on 53 and Glenn Maxwell 14 not out at the Sir Vivian Richards Stadium. Australia’s win put them top of Group 1, ahead of India thanks to a slightly superior net run-rate. Bangladesh are fourth in the group behind Afghanistan, who lost their first Super Eight match to India. The top two sides at the end of the phase qualify for the semi-finals. Test and one-day skipper Cummins bowled Mahmudullah for two, had Mahedi Hasan caught for a duck by Adam Zampa at deep third man and then dismissed Towhid Hridoy for 40 when the batter scooped to Hazlewood.
