Former Australia batsman Damien Martyn:, external A fantastic display today by India. Far too good in all areas. They are a side in very dangerous form leading into the semi-finals.
It had been largely a foregone conclusion for the last hour or so, but a professional performance from India has closed out victory. Yadav finishes with 4-31 from nine overs - India have taken all 10 opposition wickets in all seven games of this tournament - but my rupee would be on Rohit Sharma winning the man of the match award for his century.

"India are peaking at the right time. It was a clinical performance as they made more than 300. Bangladesh are honourable in defeat, and they have done their country proud."

INDIA BEAT BANGLADESH BY 109 RUNS WITH FIVE OVERS TO SPARE AND REACH WORLD CUP SEMI-FINAL
And it's all over before last man Taskin Ahmed can even face a ball - as Sabbir hooks one down fine leg's throat and India have won.

"India look very powerful. Fielding today outstanding. And they will be difficult to beat in Sydney if there's any grip in the pitch."
But when he does connect, the ball skews into the air over square leg, Ashwin takes the catch and it's a third wicket for Yadav. Will he be spared the Australian Channel 9 cartoon duck to accompany him back to the pavilion?

Rubel Hossain is the new batsman, he impressed with the ball today but with a highest score of 17 in 58 previous ODIs, it's fair to say he's not in the side for his batting. Sabbir lifts the ball over square leg, safely, and they run one. Rubel ducks under a bouncer from the hostile Yadav, he then can't connect with an attempted pull shot.

"It was almost like a half appeal from Dhoni and the bowler. India are just winding down, there is not much emotion in the celebration. They know this game is done and dusted."

A pretty miserable day for Mortaza concludes as he feathers an edge to the keeper while trying to keep out a yorker, there's only a half-hearted appeal but the umpire sends him on his way.

"A cricket match should never go nowhere. I'm afraid this match is going nowhere."
Captain Mashrafe Mortaza to the crease, with a frankly unlikely target of 114 needed from 42 balls. He's quickly on strike after a single from Sabbir, and knocks his first ball for one.

"It was an enterprising knock. But they are seven down and this game might not have long left. The spin of India may be their ace. These are the defending champions and they are an impressive outfit."

But Nasir's cameo innings ends as after whacking another four through mid-wicket, he eyes up a third successive boundary and pokes a low catch to Rohit Sharma at cover. His 35 came from 34 balls.
Chris: I completely disagree with Donald Parish (21st over), the way England handled their preparation was unprofessional. To change your captain with weeks to go, with another batsman who is not performing, showed a lack of leadership. England should have made that decision a year earlier or kept Cook and swapped Morgan out. England still wouldn't have won the cup, but they would have at least got to the quarters.
Just at the spell of the innings when India were moving into top gear, Bangladesh - with a required rate of 15.5 - are still stuck in second. Sabbir reverse-sweeps and misses, and the Tigers run a bye. Nasir gives Jadeja the charge, trying to hit over the top, and the ball flies off an edge for four as he becomes the first Bangladesh batsman to pass 30.
David McIlroy: World Cup has become formulaic: bat first, score 300, game over. Runs are great but close finishes are memorable.
Mohit Sharma's back on, he's not bowled since the 15th over - and the game has gone away from Bangladesh in the interim. Nasir pulls his fourth four to move to 25 - Bangladesh have had six men in the 20s today, but Soumya Sarkar with 29 is still the highest scorer at this stage. For the second successive over, Nasir steals the strike with a single off the last ball.

"For some reason, a whole flock of seagulls have arrived at the MCG this evening. They weren't here earlier. Where have they been? Why come now? Did they not know it was a 2.30 start? Maybe they could only get here after work? Reminds me of last summer's Headingley Test, where one pigeon stood at square leg/extra cover throughout."
