Nottingham: Australia moved closer to the World Cup semi-finals after David Warner inspired the defending champions to a comfortable 48-run win over a combative Bangladesh with his second century of the tournament.
The left-handed opener contained his natural aggressive self before swinging his arms freely to build a 166-run knock, which steered Australia to a mammoth 381 for five, their second highest score in World Cup.
Warner, who had hit a hundred against Pakistan as well, added 121 runs with his skipper Aaron Finch (53) in a risk-free opening partnership and then raised a 192-run stand with Usman Khawaja (89).
He completed his 16th ODI hundred, his sixth 150-plus knock, which came off 147 balls with 14 hits to the fence and five over the ropes.
The stage was set to go after the bowlers and Glenn Maxwell produced a 10-ball 32, which had three sixes and two fours. Maxwell was run out after a mix-up with Khawaja, who sent his partner back sensing risk and was caught behind minutes later to miss out on a hundred.
Faced with a daunting task to chase down the massive target, the 'Tigers', as expected, took the fight to the rival camp but ended up with 333 for eighth in stipulated overs.
Mushfiqur Rahim (102 not out), Mahmudullah (69), Tamim Iqbal (62) and in-form Shakib Al Hasan (41) gave their all in the chase but the effort still proved insufficient though the total was their best ever in ODIs.
It was Rahim's first hundred in a World Cup game and seventh overall. Paceman Mitchell Starc (2/55) and Nathan Coulter-Nile (2/58) shared four wickets between them.
The win took Australia to top of the table with 10 points from six games while Bangladesh remained at number five with five points and now need to win their remaining three games.
Earlier, medium pacer Soumya Sarkar (3/58) took three wickets while Mutsafizur Rehman (1/69) accounted for one Australian batsman.
Mashrafe Mortaza and Rehman largely remained disciplined in their opening spells, bowling wicket-to-wicket. Warner and Finch also preferred playing a risk-free game and did not attack much, managing an under-six run-rate.
It was only after spinners — Shakib and Mehidy Hasan — were introduced that the two batsmen showed some aggression. Warner launched one from Shakib for a massive six over mid-wicket while Finch punished Hasan with back-to-back shots over the ropes.
Paceman Rubel Hossain bowled in good rhythm and the run-rate was under control, but both Warner and Finch were still at the crease, having completed their half-centuries.
Sarkar brought relief for a worried Bangladesh by sending back Finch with his fifth ball in what was a soft dismissal off the medium pacer in the 21st over of the innings.
But the joy was short-lived as Warner and Khawaja joined forces to raise another big partnership. They added 192 runs for the second wicket, dominating the bowlers.
Sarkar again separated the batsmen by dismissing Warner but by that time, Australia had already 300-plus total on the board.

Put in to bat, Bairstow (53 off 48) scored his second fifty of the tournament, while David Warner (45 off 33) and Kane Williamson (41 off 26) also came up with valuable contributions, helping Sunrisers Hyderabad post a competitive 162 for four.
RCB, coached by Simon Katich with Mike Hesson as Director of Cricket, have won all of their opening games between 2011 and 2016, but have only made the finals twice during this period.
David Warner is happy to have the presence of experienced campaigners such as Kane Williamson in the Sunrisers ranks.
