MS Dhoni hails spirit as India cruise into semi-finals of Cricket World Cup

India captain Mahendra Singh Dhoni praised his team for their spirited revival after storming into the World Cup semi-finals on Thursday.

India's Rohit Sharma stroked an authoritative century and Umesh Yadav claimed four wickets to help defending champions India advance with a 109-run win over Bangladesh at the Melbourne Cricket Ground.

Sharma scored 137 off just 126 balls with 14 boundaries and three sixes, sharing a 122-run fourth-wicket partnership with Suresh Raina (65) to help India reach 302-6 after some tight Bangladesh bowling contained much of the innings.

Bangladesh, playing in the quarter-finals of the Cup for the first time, fell away in the run chase and were bowled out for 193 in 45 overs, but won plenty of admirers with their performances during the tournament.

"It has been good. We can't shy away from the fact that we are playing some good cricket," Dhoni said.

"A month back we were struggling. A lot of credit needs to go to the boys and the support staff."

India had not won a competitive match in the two months leading up to the World Cup, but have now won seven straight to give Dhoni his 100th ODI win as India captain.

Dhoni said he was especially pleased with the overall health of their game.
