India have secured their place in the quarter-finals of the Cricket World Cup with a four-wicket victory over West Indies.

After West Indies were bowled out for 182, India initially struggled with their run chase before a nerve-settling knock of 45 from skipper MS Dhoni ensured that his team prevailed with 10.5 overs to spare.

Despite winning the toss, West Indies struggled to find their feet and when Chris Gayle was dismissed for 21, they found themselves on 35-3 after nine overs.

India kept on the attack with several of their bowlers chipping in with wickets, and when the West Indies had been reduced to 85-7 at the halfway stage, it appeared as though they were in danger of being bowled out for double figures.

However, a patient 26 from Darren Sammy was followed by a knock of 57 off 64 balls from Jason Holder, and that innings helped to take the West Indies to 182 all out.

Given the number of high scores at the tournament, chasing 183 should have proven routine for India, but they were soon on the defensive after Jerome Taylor removed both opening batsmen.

Virat Kohli contributed 33, but after he and Ajinkya Rahane got out, Dhoni was left with a rebuilding job when he made his way to the crease at 78-4.

He was briefly supported by Suresh Raina and Ravindra Jadeja, but it was the Indian captain who took centre stage with a patient innings to take his side to the brink of victory.

Ravichandran Ashwin played the support role at the other end, scoring 16 off 32 balls, but Dhoni sealed the triumph in style with a six and a four to maintain India's 100% record.
