An unbeaten century from Gautam Gambhir and a blistering fifty by Virender Sehwag led India to victory over Bangladesh.

Sehwag's early onslaught ensured India were never under pressure as they made light work of a target of 223.

India eclipsed the target in 35.1 overs, losing just three wickets in the process, and will take on Pakistan in the final on Saturday.

Bangladesh were bowled out for 222 in 49.5 overs, the bulk of the runs coming off the bat of Raqibul Hasan (89).

RP Singh, India's only change from the team that humbled Pakistan on Tuesday, was the pick of the bowlers, claiming three for 46.

Sehwag, who plundered 89 runs in India's 140-run win over Pakistan, continued from where he left off as he cut and pulled Bangladesh's bowlers in typically ferocious fashion.

He brought up his half century in just 29 deliveries, but departed soon after while attempting to hook Dolar Mahmud.

Sehwag (59) had hit Mahmud for a couple of sixes and fours, but the bowler had the last laugh when he snared the opener off the last delivery in his expensive first over.

India's innings lost momentum following Sehwag's dismissal as Rohit Sharma laboured to 26 before falling to a mistimed sweep.

But, Yuvraj Singh (26), who was dismissed when at the doorstep of victory, got the chase back up to speed.

Ghambir was cautious at the start, content with watching as Sehwag took centre-stage.

But the left-hander slowly came into his own as he dominated the chase. His unbeaten 107 came off just 101 deliveries and contained 14 boundaries and a six.

Earlier, Hasan's knock had bailed out Bangladesh after the loss of early wickets effectively ended the hosts' hopes of making the final.

Medium pacer Praveen Kumar, again handed the new ball, struck in the very first over, getting Tamim Iqbal to edge a wide delivery to wicketkeeper Mahendra Singh Dhoni.

RP Singh, who came in for Ishant Sharma, removed the other opener, Shariar Nafees, to leave Bangladesh in trouble.

It was left to the 20-year-old Hasan and skipper Mohammad Ashraful to repair the damage.

The two battled hard against a nagging line from India's bowlers - and their task got even harder once Dhoni deployed the spinners.

Ashraful, out of sorts at the start when he edged a couple of deliveries past the keeper, steadied the ship but only briefly.

Just when he seemed to have weathered the storm, he handed part-time off-spinner Yusuf Pathan a tame return catch ending his innings on 36.

Yusuf was brought on after specialist spinner Piyush Chawla went wicketless in his first four overs. But soon after, Chawla had Mushfiqur Rahim (6) dismissed cheaply.

Irfan Pathan, half-brother to Yusuf, had no joy either in the initial overs, but later came back to claim the wicket of Alok Kapali (20), who had threatened from the start.

Through it all, Hasan batted with increasing confidence, reaching his maiden ODI fifty in 79 deliveries.

Cramps and a better line from RP Singh denied the youngster a century.

He fell attempting to pull RP Singh for a boundary, but only found Praveen Kumar at mid-on.

Mahmudullah (24) got the hosts beyond the 200-run mark even though a couple of runs outs at the death brought the innings to an abrupt end.
