Rohit Sharma led India into the semi-finals of the World Cup with a 109-run victory over Bangladesh at the MCG, and then said his team was well on course to defend the title.

After India's seventh win in a row, Sharma said: "We just need to do what we've been doing. We're doing the right things on the field. When batting, we're creating partnerships and the bowlers are bowling in tandem and taking wickets."

Sharma's imperious 137 provided the backbone of India's innings as they made 302 for six. Umesh Yadav then took four for 31 to restrict Bangladesh, who were all out for 193.

Darren Sammy is hoping West Indies can deliver a 'Buster Douglas' knockout blow for New Zealand in the fourth quarter-final in Wellington.

The Windies all-rounder, and former captain, likened his team to Douglas and the Kiwis to Mike Tyson, who was stunned 25 years ago by the unfancied Douglas and his one knockout punch.

After New Zealand's unbeaten group campaign, Sammy acknowledges the co-hosts will start favourites but he said: "It's a big match, but I remember some guy named Douglas beating Mike Tyson. It is a case of that on Saturday."

West Indies have a far superior pedigree to this weekend's opponents in the global tournament, albeit historical.

"We've won two, but it's been a long time - and New Zealand have not won any," said Sammy, who senses a new intensity among teams who have made it this far.

"It's just a different feel. It is the business end. You can win all your games in the preliminary round - but in knockouts, there is no guarantee you're going to win.

"The guys know what is at stake, and we're going to do everything in our power to beat 'Mike Tyson'."
