Our first look at off-spinner Ravichandran Ashwin, who would probably have woken up this morning hoping to outfox some top-order batsmen. Well, he won't get that chance, but he could still have a big part to play here. Two singles off a tidy first over.

West Indies 42-4 (11 overs)

Batsmen: Carter 2, Simmons 2

Fall of wickets: 8-1 (Smith 6), 15-2 (Samuels 2), 35-3 (Gayle 21), 35-4 (Ramdin 0)

Live TMS commentary

Massive rebuilding for this duo - the experienced Simmons and the relatively callow Carter - with the first powerplay out of the way. India's fast bowling continues to be one of the surprise success stories of this tournament. First runs for Carter, working Sami to long leg for two.

Lendl Simmons is the new man, joining Jonathan Carter, whose promotion up the order to number four went pretty much unnoticed amid that chaos. Simmons gets a gift first up, easing a full ball off his legs for three.

Bad to worse. Denesh Ramdin trots out, takes guard, and drags his first ball onto his timbers, sparking pandemomium among the India fans in the stands. Disaster for the West Indies, due reward for some excellent bowling from India.

"It wasn't short enough to pull and he didn't move his feet. India will be very happy. They deserved that wicket because they have bowled excellently today."

This is suicidal cricket from Chris Gayle. Just when he was starting to find his range, he aims an ugly leg-side heave at Shami and skies it way up in the air to give Mohit a simple catch at deep square leg. Totally unnecessary, as it was the last ball of the over and Gayle had already cracked Shami for four. Tellingly, the bowler doesn't even really celebrate, he just has his hands on his hips in apparent bewilderment.

Chris Gayle is angry. Finally he connects, launching Yadav over mid-off for a one-bounce four. Next ball, he gets another reprieve - his third of the innings - when he slices to third man again, this time Shami puts it down.

Then he ends an eventful over by blasting an absolutely towering six into the stands at midwicket. Switch flicked?

"For me if I was a West Indian fan right now I would be livid. This is not what you expect at a World Cup. This should be the best of the best and they are just all at sea at the moment."

This is an absolute shambles. Gayle, still looking all at sea, tries to swing the ball over the infield on the off-side but mistimes it and loops the ball up towards Mohit Sharma at mid-on. It lands just short of the fielder, but when he looks up, he finds that Samuels has joined Gayle at the striker's end and has the simple task of lobbing the ball to Virat Kohli to whip the bails off.

Gayle just cannot get bat on ball on the moment. He finds fresh air with a leaden-footed swipe at Shami, then skips down the track with the same result. Plenty in this surface for the seamers, and Shami gets a venomous short ball to rise past Gayle's helmet.

India's seamers are bowling clever lines here, wide but not too wide, leaving the batsman, not allowing Gayle to feel the reassuring sensation of willow on leather. Finally, the West Indies opener cracks. He has a wild heave at a wide one and sends the ball spiralling towards third man, where Yadav takes a brilliant tumbling catch, only to see the ball jolted from his grasp when he crashes back to earth. How costly could that be?

Gayle is finally off the mark after 11 balls, tucking Yadav off his legs for a single. Those are the first runs off the bat since the second over.

This World Cup has shown that slow starts aren't necessarily as costly in the modern game as you might have thought a few years ago - with Exhibit A being Pakistan's win against Zimbabwe the other day. West Indies will hope that's the case today, but India are not Zimbabwe, and they're being given a big head start in this match.

Marlon Samuels is the new man, and he gets a steepling short ball from a fired-up Shami first up.

"I think a few West Indies supporters will be on their feet, thankful that he is out. Smith looked like he was working for the Indians there at one stage, and finally he gets a little feather. He batted like a tail-ender, he looked all at sea."

It's fair to say that had been coming. Smith has really struggled to time the ball in this innings, foxed by a combination of late movement and high bounce, and with no runs off the bat in three overs, the pressure tells and he tries to cut a ball that was too close for comfort. A thin edge through to the jubilant Dhoni is the result.

Gayle is a magnificent, monstrous batsman in full flight but he can be a very sticky starter. Umesh Yadav has really found his areas early on, sliding the ball across Gayle on off stump, and the batsman can't get willow on leather at the moment.

When Yadav does err on Gayle's legs, good fielding at square leg keeps Gayle on strike. Another maiden, early pressure building on West Indies here.
