Eoin Morgan smashed a century yesterday to bring England back from the brink to win the second one-day international against Bangladesh.

The Irishman hit a masterful 110 not out in Mirpur to carry England past their target of 261 with seven balls to spare, and only two wickets in hand, after the Tigers had bowled themselves into pole position.

The result maintained England's 100 per cent record against the hosts in 14 meetings and secured a series win with one game to play.

Morgan moved beyond three figures for the first time in England colours during a penultimate over that he thrashed for 16, but did not even raise his bat to mark the occasion.

Instead, he took guard once more and heaved Shafiul Islam for six to win the match and silence a raucous home crowd.

"The hundred certainly wasn't something I was thinking about, I must say," said Morgan. "It was all about the short boundary and where I was going to hit it.

"But it's my first hundred for England and that is obviously a great experience; it's also something to get out of the way because I hope there's more success on the way. It's certainly up there with my best innings. Everything went to plan."

Captain Alastair Cook, who made it two wins from two leading the side, made a positive 60 to continue his own good form but was quick to defer to his finisher.

"It was a fantastic knock, it had everything," said Cook.

"He was probably the coolest person out there because I certainly wasn't, I was pacing up and down the dressing room."

England's situation when Morgan grabbed the win was even more precarious than the batsman knew.

Stuart Broad was due in at number 11 after experiencing discomfort in his back and, unknown to Morgan, Matt Prior was padded up to join him in the middle as a runner. Fellow seamer Ryan Sidebottom had already been ruled out of the one-day series with a thigh injury before play, while Test player Graham Onions is thought to be having back trouble of his own.

Cook said that the extent of the side's fitness concerns was not yet clear.

"Broady, we're not sure about. Obviously he has a bit of a bad back but we need to give it 24 to 48 hours for it to settle down before we can give any proper assessment," he said.

Somerset's Craig Kieswetter made just four runs.
