Today in Chennai, one of the greatest sportsmen of his or any generation will attempt to reach a milestone that until recently many had not even realised existed. If seeing history in the making interests you, I reckon you might want to stick around.

The legend is question is Sachin Tendulkar, a man who has scored 32,645 runs in an Indian shirt. If he scores a century in their Group B match against West Indies at the World Cup, he will have scored 100 100s for his country. It's impossible to overstate the size of this achievement. My esteemed cricket editor Paul Grunill likenes it to "climbing Everest on top of Everest". He's rarely wrong.

I asked Tendulkar, and he said he'd only score his hundredth hundred if you lot got stuck in with chat all day long*. Here's how: text to 81111 (with 'CRICKET' at the front of your message); tweet me @Stevo_football; tweet me with the hashtag #bbcworldcup; and send an email e-mail to tms@bbc.co.uk with 'For Jonathan Stevenson' as the subject.

* Strictly speaking, this isn't true.

India have won the toss in Chennai and are going to have a bat. So if Sachin Tendulkar is going to reach that landmark, it'll probably happen in the next couple of hours. Get the teas in; this is what we're here for.

So, here's where we are in the World Cup: India and West Indies have both already qualified for the quarter-finals. Actually, Windies are only 99.99% assured of their place, but they would have to receive the kicking of a lifetime today to not get through. If India win, they will finish second in Group B and will play Australia in the quarters. Windies could finish second or fourth. It's a bit complicated, really.

Some team news to fill you in on - India have made two changes, with Suresh Raina replacing injured opener Virender Sehwag and off-spinner Ravichandran Ashwin, on his home ground, coming in for left-arm fast bowler Ashish Nehra. West Indies leave out star batsman Chris Gayle, who had been an injury doubt, for Kirk Edwards, while fast bowler Kemar Roach is rested and Ravi Rampaul comes in.

From Herbie in the TMS inbox: "Is there any result that means Bangladesh would go through at the expense of West Indies?"

(From Paul Grunill) Realistically, no......I'm not a mathematician but India would have to win by, to use the vernacular, 'shed loads'.

Sachin Tendulkar and Gautam Gambhir walk to the wicket in Chennai and they get a thunderous ovation from the crowd, who are already unbelievably lively. Excited? You will be. Our bid for 100 100s starts here...

From Phil, Adelaide, in the TMS inbox: "I hope India win but no 100 for the Master. That way they will play Australia, whose skipper, Ponting, said he knew he'd nicked it to Akmal yesterday. For Tendulkar, the epitomy of sportsmanship, to achieve such a milestone against his complete opposite would be delicious. Oh the polarity!"

Unbelievable. If there's a silver lining, it's that Sachin Tendulkar's show of sportsmanship has shown that gentlemanly conduct in cricket is still alive and kicking. The appeal went up from Rampaul, the umpire hadn't decided, and Tendulkar walked without even looking. I wonder if Ricky Ponting's watching...

From deafening roar to deafening silence. It's gone a bit eerie in Chennai. Big Sulieman Benn lopes in for the second over, the left-arm spinner bang on the money, but Gambhir won't let him settle, dancing down the pitch to the last ball and whacking him over mid-wicket for four.

From Mo, London, in the TMS inbox: "Stevo, it is hard to see how anyone can get close to the little master. It's often stated that genius's also have a weakness of sort, Zidane, Schumacher etc. But this guy is one that defies that 'rule'. Class act."

Rampaul is getting some serious bounce, and I didn't even tell you who the new batter was did I? How rude. It's Virat Kohli, and he and Gambhir take three off the over with minimum fuss.

Benn comes round the wicket to Kohli, not going between umpire and stumps as I used to but around the umpire. To be fair, he's about twice the size of me, so the umpire would have to stand about 10 yards back. Over the wicket to Gambhir, who is watchful, until Benn drops short and he rocks back and cuts hard through point for four.

Rampaul is extracting life out of this pitch as another bouncer flies past the helmet of Gambhir. He's bowling short of a length and getting it to rear and the classically moody stares of a fast bowler are there in abundance too. Gambhir nicks one that flies in the gap between first slip and gully for four, unlucky Ramps.

From Mo, London, in the TMS inbox: "There you go Stevo, that's what separates him [Tendulkar] from everyone else. There was no way they would have given that out even if they had reviewed it. Only he knew he nicked it and he walked. Century against the Aussies, hopefully."

Benn continues, this giant of a man bowling spin, he gets one to bounce on Kohli and the right-hander is beaten attempting a cut shot. But he feasts on to a fuller ball, devouring it through the covers for four... and Benn over-pitches again, Kohli once more clubbing him to the offside fence. Glorious batting, and probably the end of Benn, for now.

Windies need pace - or at least bounce - from both ends, according to Tony Cozier, the "doyen of West Indian cricket", says my colleague. Rampaul bowls a decent over but Gambhir plays a peachy shot from the fifth ball, rocking back and caressing a ball just short of a length in-between cover and point for four.

Here's that change as Andre Russell comes on for Benn. It's right-arm medium-fast and he finds a decent line and length to both batsmen straight away, conceding three singles before getting excited and bowling a bouncer that flies over poor Devon Thomas's head and runs away for four byes. Ruined the over, that.

Yuvraj Singh is the new batsman and, as you'd expect, he gets a pretty healthy ovation from the Chennai locals. He hasn't faced yet as the batsmen crossed, and Kohli clips a couple more past square leg.

So, Russell to Yuvraj, bouncer first up and the left-hander is forced back. He'll be expecting some chin music, no doubt. Russell pings another in short of a length and Yuvraj doesn't look entirely comfortable, a very fine maiden over.

West Indies take the bowling powerplay, as is standard, and Rampaul fizzes in a short bouncer that Yuvraj tries to flay away and misses completely. He has more luck next ball, though - a ball back of a length enables him to step back and bludgeon the ball through mid-wicket for four. There's the crowd again.

From Kev, Wellington, in the TMS inbox: "With the DRS now here to stay, should there be a directive from the ICC to umpires to make positive 'out' decisions against those batsmen who choose not to walk (not mentioning any names - i cant be bothered to name the Australian team) and force them into making a decision? It would surely encourage more sportsmanlike behaviour as demonstrated by Sachin and Adam Gilchrist and any 'howlers' would still be rectified."
 

A frustrated-looking Russell rages in, like a big ball of energy, but his radar has gone off a little and both Kohli and Yuvraj are playing him quite comfortably. Yuvraj hammers the last ball of the over straight to Devon Smith at point, his timing's not quite right on that occasion.

Sammy is clipped away for a couple by Kohli before Yuvraj seizes on a short ball that pops up outside off stump, the left-hander pirouetting in his crease and swinging it away through the leg side for four. Bowling powerplay over, for what it's worth.

Leg spinner Devendra Bishoo, who bowled wonderfully against England the other day to take 3-34, comes on and Yuvraj has a look before pulling a short ball into the leg side for a single. Like the looks of this boy Bishoo, who elicits an outside edge from Kohli off the last delivery, the ball running away for four. Moral victory for Bishoo.

From Jaco, Pretoria, in the TMS inbox: "Regarding the TMS producer's tweet that there were "no heroics from the little master today", I disagree. We did see heroics. Not the kind of heroics that the Ponting's of this world would understand or appreciate, but heroics nonetheless."

Bishoo continues. My editor Paul reckons he sounds like a cross between the noise you make when you sneeze and what the person next to you says as a result of said sneeze. Bang on the money, two off it.

Sammy continues to trundle in without too much happening. Kohli has been quiet just recently, gone into his shell a little. Still got 36 from 44 balls, mind. Get in touch, will you? Text 81111, tweet @Stevo_football or with the hashtag #bbcworldcup or send an e-mail to tms@bbc.co.uk with 'For Jonathan Stevenson' as the subject.

Bishoo finds his line and length almost unerringly, very impressive for an inexperienced leg spinner. He's not giving Kohli or Yuvraj anything to hit, the left-hander missing a drive, almost nicked that to Devon Thomas. Three overs for nine so far for Bishoo.

Sammy is on the money and into a nice rhythm, until Yuvraj takes two steps down the wicket, swings those powerful arms of his and plants the West Indies captain miles and miles over long-on and into the crowd. Effortless, sublime, scintillating. A bouncer ends the over, Yuvraj getting the heck out of the way.

Now Yuvraj goes after Bishoo, slogging a sweep into the air and to the square leg boundary for four. Bishoo keeps his cool and there are three more singles off the over. Signs of intent from Yuvraj.

Big-hitting middle order batsman Kieron Pollard is on to bowl some medium pace for the West Indies and Kohli scampers through for a quick single just as his stumps are thrown down. Four singles off the over, the last ball rearing unpleasantly off a length at Yuvraj, who reacts with genuine surprise.

Bishoo draws a false shot from Yuvraj, the left-hander clipping a shot into the leg side and into the air, the ball falling just short of mid-wicket. Four off the over. A Mexican wave starts up in Chennai - it's not that dull. Behave.

From Chris, Stoke-on-Trent, in the TMS inbox: "Re: comments on batsmen walking - players are far more likely to walk when they've nicked it while the DRS is in place as if it's an obvious deviation the umpire's original decision will be changed anyway."
 

Pollard is steered intelligently down to third man for four by Virat Kohli, lovely touch that. The big man recovers well though, four dot balls to end the over, five from it. Kohli has 46 from 62, Yuvraj 43 from 58 balls.

Finally the pressure of bowling to Yuvraj gets to Bishoo. His first ball is too full and Yuvraj's quick feet turn it into a full toss, the left-hander hammering it into the leg side for four. Next ball is flat and down leg side, Yuvraj swivelling and spanking it down to fine leg for four more, that's brought up his fourth fifty of the World Cup. Three more runs off the over, Yuvraj hogs the strike, and 11 off that one.

From Andrew in the TMS inbox: "Everyone is saying how much Sachin showed sportsmanship today, has everyone forgotten what happened two weeks ago between England & South Africa, Jacques Kallis ASKING Matt Prior if he caught it because he knew he nicked it but the umpire hadn't even moved, Prior said yes so Kallis walked, yet no-one seems to mention it."

Pollard tries to becalm Yuvraj, bowling just short of a length and Yuvraj popping one up that stops on him just short of Devon Smith at point. He swings his arms next ball and takes two to the cover boundary, three from the over.

Sulieman Benn comes back on for Bishoo and he is a touch short first ball, Yuvraj leaning back and cutting with immense power for four. Benn then over-pitches and Yuvraj creams him gloriously through the covers for four more, he's racing here, no mistake. Benn is usually a Windies banker, but his four overs have gone for 32.

Pollard jogs in, over-pitching as Kohli this time hammers him away to the mid-wicket boundary for a one-bounce four and that has brought up his half-century, from 64 balls. These boys have now put on 104 in just over 20 overs.

Double the score after 30 overs and West Indies are looking at a run chase and a half. Andre Russell comes back on with the Windies really needing to break this stand and Yuvraj looks exhausted, so umpire Steve Davis calls for a drink mid-over, strangely. Five off the over.

From Jackie, Melbourne, in the TMS inbox: "Why can't I follow the commentary of this game, as a neutral, without hearing the Aussie bashing? We are not even playing for goodness sake! What is it with you Poms, this obsession with beating Australia and knocking us. You know, we actually kinda like the the English over here. We enjoy your eccentricties and especially enjoy how uptight you get when you are supporting your team!"

Years and years and years and years of losing. That explain it?

Windies turn to Rampaul in their desperation for a wicket, an obvious choice as he's taken the only two to fall so far. But these two are batting like they are in a dream, completely unperturbed by anything going on around them. Five singles off the over.

From Tim, Marlow, in the TMS inbox: "Stevo, listening to a match featuring Sulieman Benn reminds me of the time that an elderly relative of mine (whose identity is withheld to protect the innocent) wondered aloud whether he was any relation to Tony Benn. Quite possibly the silliest sporting question I have ever heard."

Russell starts his sixth over with a leg side wide, before Kohli pulls him to deep mid-wicket for a single. Yuvraj takes two with an effortless flick off his pads and gets two more to extra-cover, lovely shot off the back foot. Eight off it.

From Mark, TMS inbox: "Re Jackie in Melbourne. Don't be so defensive, people are not having a go at Australia, they are having a go at Ricky Ponting. Last time I looked they are not the same thing. Which must come as a comfort."

India captain MS Dhoni comes in and he gets a pretty enormous ovation too. Yuvraj takes advantage of the wicket to dash off the pitch for a minute as everyone else takes drinks. Dhoni is off the mark straight away to long-on, good over though, three off it and Rampaul has 3-38 from eight overs.

Remember, if India win today they will face holders Australia in the quarter-finals. Dhoni pushes Russell to Sammy at cover but it goes straight through the captain's legs - nutmegged - and they take a single. Four off the over, very much calm before the storm. Yuvraj has 81 from 91 balls.

The ball is changed, as is mandatory after 34 overs, but Yuvraj continues, his flashing blade sending a Kieron Pollard ball outside off stump to the deep backward point fence for four. This is now Yuvraj's highest score in World Cups, would you believe? He clubs Pollard to long-on, one bounce to Devon Smith, who was mulling over a dive and attempted catch for a split second.

Devendra Bishoo is back on and pushing it through a bit more, he's probably a bit worried about floating it up and being thwacked out the ground, can't blame him. Four singles off the over and he'd have settled for that, for sure.

Pollard continues to amble in, both Yuvraj and Dhoni are circumspect for now, gearing themselves up for a heroic finish. Dhoni cuts fiercely for a couple off the last ball, while Yuvraj is down on his knees at the other end, he looks like he's really struggling, dehydration maybe.

From AJ in the TMS inbox: "Re Mark (below) - Ricky Ponting has a 34-1 World Cup record as Captain. English would dream of such a cricketer, with that sort of record."

Nothing like a bit of English-Aussie banter, is there? Amazingly, no mention of the Ashes from anyone so far... Anyway, Bishoo continues to wheel away, probably relieved he's bowling now and not in seven, eight overs' time. Having said that, Yuvraj sweeps a poor ball down leg side for four. He's now 96 not out.

Dhoni sends his Chennai public wild by dancing down the track to Pollard and larruping him over mid-wicket for four, brutal shot. He then steals a single into the off side to get Yuvraj, on 96, on strike. Yuvraj garners a single of his own, toying with the crowd, six off the over.

Bishoo sizzles a couple of quick, flat leggies into Dhoni and he's not giving them any room to have a crash. Three singles off the over - two to Yuvraj, who is now 99 not out and on strike. When he reaches three figures, he's going to swing for everything.

Dhoni edges streakily and gets a couple after a mis-field from Benn, long way for him to get down in all fairness. And still we wait for the carnage...

Suresh Raina, the 24-year-old left-hander, walks to the crease for the first time in this World Cup. He gets off the mark with a single and Bishoo finishes with 1-48 from his 10 overs, good effort.

Pollard continues and Raina picks up a couple to the cover-point boundary, nice stroke. A ball from Pollard bounces on Raina and Devon Thomas cannot collect, the wicket-keeper falling to the ground straight after, looks like he's picked up an injury, possibly his right thumb. Yuvraj takes advantage of another rest to drape a towel around his head and sit on the floor. Thomas is patched up, and after a five-minute break we continue. Both men are struggling.

West Indies have done well here, so far they have avoided the carnage the Chennai crowd was expecting India to create. Yusuf Pathan comes in, about time he showcased his class to the World Cup.

From Graham in the TMS inbox: "It is now evident that England's erratic progress in the group stages was all part of a masterly plan to avoid Australia in the quarter-finals."

Now India take the batting powerplay, as we enter the final five overs, so West Indies can only have a maximum of three fielders outside the 30-metre circle. Andre Russell is back and it's short, outside off stump, so Pathan helps it on its way past the keeper for four, very fine shot in every sense. Harbhajan gets off the mark with a single off his first ball before Pathan pulls hard but Pollard cuts it off running around at long-on, top fielding.

India are blowing their chances of a big total here, though with Chris Gayle left out by West Indies it certainly won't be an easy run chase. Chennai local Ravichandran Ashwin is next man in and he should be run out taking a single, Sammy missing with his throw from mid-off. Rampaul then sneaks one through Harbhajan's defences, just misses everything, great over.

India have only gone and collapsed again, haven't they? It's awful quiet in Chennai right now. Ashwin takes a single off the last ball of the over, so new batter Zaheer Khan won't have to face yet.

India are in danger of being bowled out yet again here. Strange World Cup gets strangers. Munaf Patel gets off the mark with a single and Ravi Rampaul ends with 5-51 from his 10 overs.

India are bowled out for 268 in 49.1 overs. West Indies need 269 to beat the hosts.

West Indies bowler Ravi Rampaul after collecting 5-51 on his World Cup debut: "I went out and did my best for the team. Earlier I had a lot of bounce, like with the first delivery and then I bowled line and length and it paid off. [Towards the end] I got a bit of reverse swing and bowled a few yorkers and it worked. It's an awesome crowd and I like the atmosphere."

Great effort from Ravi Ramps, that. I'm gonna lie low for a while, but you won't miss the start of the West Indies run chase, oh no. Stay in touch though, won't you - texts go to 81111 (put 'CRICKET' at the start), tweets go to @Stevo_football or with the hashtag #bbcworldcup and you can email tms@bbc.co.uk as well, with 'For Stevo' in the subject.

From James, Bristol, in the TMS inbox: "I met Ravi Rampaul's dad at a breakfast diner in New York. Nice bloke. We shared a waffle."

No rest for the wicked. Off spinner Ravichandran Ashwin is opening the bowling for India and we're getting under way.

Ashwin bowls three long-hops and gets away with all of them, Devon Smith steadfastly refusing to play an aggressive shot in the face of such dire bowling. Kirk Edwards is his partner and he blocks his first two deliveries.

Zaheer Khan steams in from the other end and Smith clatters him to Kohli at backward point, good stop from the half-centurion. Smith totally misses an attemped drive before cutting late and superbly for four. Classy.

Ashwin, who looks quite gangly in his action, is being cheered every ball by his home Chennai crowd, but they are silenced as Edwards caresses him through the covers for four.

Zaheer is struggling a touch for line here against a left- and right-hander, just straying on to the pads. Smith plays a quite stunning drive off the front foot, straight back past the stumps for four. Pathan then throws down the stumps at the non-striker's end, umpire Simon Taufel doesn't go upstairs - but replays show he would have been out. That's unbelievable. He's a foot out, Edwards. Unbelievable.

I'm still reeling from that non-decision. Ashwin squares Smith up, leading edge to cover, and India are unluckly not to have a breakthrough so far. Four off another steady over.

India get Harbhajan Singh on quick-sharp and he beats Smith's outside edge with an off spinning beauty first up. Edwards takes a couple into the covers before he moseys down the pitch and blasts Harbhajan into the crowd for six over long-off. Good intent.

Darren Bravo is in at three and he will have a big part to play if West Indies are going to get anywhere near this total. He's off the mark, good over from Ashwin, only three off it.

Smith cuts Harbhajan hard, but Munaf gets across smartly inside the ring to prevent what might have been four. Three singles from the over, Harbhajan doing his job for Dhoni well.

From Andrew in the TMS inbox: "On the subject of Simon Taufel not reviewing the run out, I have a theory. A few years ago, he got into hot water by saying he goes on the appeal and the body language of the fielding side as to whether to give someone out or not - all part of the picture he paints to get him to his decision. Did the fact the Indians didn't appeal with any conviction and didn't really think it was out affect Taufel's dicision?"
 

Ashwin hasn't bowled that well but the Windies are making him look unplayable. Two singles from the over, despite another long-hop in there, and he's got 1-15 from five so far.

Harbhajan isn't so lucky as Smith leans back and chops him to the fence for four, too short by miles. One ball rears up at Smith and that's a false shot, would've been snaffled by a short leg if there was one.

The bowling powerplay is taken immediately, as if you needed me to tell you. Ashwin continues, four more singles off the over and it's all a bit tight at the moment. "Bravo looks like a batsman, you'd have to say. That swagger, that stance," says Michael Vaughan.

From Saleh in the TMS inbox: "Simon Taufel - Anagram - "Fault is on me'."

Harbhajan is wasting too many balls at the moment, one short ball forced into the leg side for two runs by Smith, before one down the leg side is helped on its way for four leg byes. Smith pulls another short ball aerially into the mid-wicket area for four, safe shot because there's no-one there.

From Tim in the TMS inbox: "Stevo, Re 3^rd over.  Am I the only reader slightly perturbed by the phrase “they are silenced as Edwards caresses him through the covers?” I thought that sort of thing only happens on The Tudors?" 

Ashwin is out-bowling Harbhajan comfortably at the moment. Hang on scrap that, Bravo has just blazed him over long-off for six glorious runs. It's like watching a Brian Lara clone. Bravo rocks back to the last ball and clatters Ashwin through the covers for four more. Magical batting.

Yusuf Pathan is on for India and he's on the money, conceding five singles off the over. Dhoni needs a couple of wickets, because these two are rolling along no dramas.

Ashwin continues, his eighth over, and he's looked less dangerous as he's got deeper into his spell. There's half an appeal for lbw as Bravo misses a straight one but it's too high, before Smith clips a couple off his legs from the final ball of the powerplay.

Pathan has been accurate so far, only two singles off that over, he's doing a good holding job. Nothing wide, so Bravo pays him the respect he deserves. India were 86-2 at the same stage.

Pathan continues and Ramnaresh Sarwan is the new batsman. Three singles from the over, Pathan isn't doing much with the ball but he's proving difficult to get away. He's got 0-10 from three overs.

Raina is slightly back of a length and Devon Smith continues to devour anything short, cutting ferociously to the boundary for four. He gets to fifty with a push down the pitch to long-off, good knock from 63 balls that. The Windies hundred is up when Sarwan takes a quick single into the offside.

From David, TMS inbox: "Re G Boycott >13...14< overs - Could that be true, that teams are calculating the opposition they want in the next round and maybe even conspiring to lose? When does gamesmanship turn into sharp practice? I want to see cricket played between two teams trying their hardest to win."

After drinks (I think I went early with mine a couple of overs ago), Smith cuts yet another short ball outside off stump for four, surely the Indians have realised he quite likes it out there? Six from that Pathan over, might go all the way, this one.

Now Sarwan's flashing past gully for four, this time Yuvraj the guilty party as he drops it a fraction short. More spin than Alistair Campbell bowling tweakers from the Pavilion End, this Indian team. Eight from the over, a pretty ineffective one by and large.

As Munaf Patel waits on the boundary to see if he has any part to play in this game, Pathan continues, conceding three singles from that tidy over. Wonder what Dhoni's thinking.

Devon Smith unleashes, giving Yuvraj a taste of his own medicine as he saunters down the track and hoists him into the crowd over mid-wicket for the first six of his increasingly crucial innings. Eight off the over, West Indies' progress is seamless.

Pathan would struggle to bowl anyone's mum out with these gentle floaters, let alone Sir Geoffrey's. Another bizarrely harmless over sees West Indies collect two more and it's quiet in Chennai. Eerily.

They remembered him! Munaf Patel gets his turn nearly halfway through the West Indies innings, Smith driving a couple and then taking a single to the cover boundary to move into the 70s. Four from the over, Windies nearly halfway there.

Sarwan whacks Pathan over mid-wicket for four, one bounce, super classy stroke. That's a false shot as Sarwan chops uppishly, the ball falls just short of point. A drive into the off side brings two more for Sarwan.

Patel isn't looking too threatening either, he's getting a bit of bounce but doesn't look like getting anyone out. Sarwan hooks to fine leg, where Tendulkar picks the ball up on the bounce, touch risky from Sarwan. Patel then bowls short and wide to a salivating Smith, who presumably cuts to the boundary for four with dribble running down his face. They won't learn, will they?

Harbhajan Singh comes leaping and bounding back into the attack for India - surely this boy's too passionate to let the game drift away? Six dot balls = maiden over, Harbhajan giving Sarwan nothing at all to hit.

From Paul in the TMS inbox: "So am I right in thinking a Windies win would put England against Pakistan in the quarters, and an India win would put them against Sri Lanka?"

That's the way it looks, yep. Thoughts?

Patel is bowling around the wicket to Smith and he plays and misses, the crowd are back in the game with nine dot balls in a row. Smith drives and Tendulkar's throw from the boundary is way off, could've been a run-out issue there. Patel finds another false shot in Smith armoury with a slower ball. Good over, but India need wickets.

Harbhajan twirls away and Smith cuts him away for a single to bring up the West Indian 150. These two might as well be sipping rum on the beach, totally untroubled. Five from the over, India look impotent.

Here comes the big man. Kieron Pollard, one of the great hitters in the tournament, is in for West Indies. A dog wanders on to the pitch and delays us by a few moments before Pollard pushes up to long-off for a single to get off the mark. Good return from Zaheer. He's got seven overs left, too.

From Sachin, California, in the TMS inbox: "So, by now it should be clear who is facing who in the QFs? Not to me yet, as I am not sure how that is decided."

Right

West Indies wicket-keeper Devon Thomas blocks the last ball of Harbhajan's over and he must now stay with Sarwan for a few overs.

From Jonathan, London, in the TMS inbox: "Sri Lanka's got to be better for us, they've got fewer bowling options & a shorter batting line-up. Plus I wouldn't fancy our faltering batting against the likes of Gul & Afridi."

Fewer bowling options? You've got to be kidding me.

Zaheer races in and beats Thomas's outside edge, beautiful left-arm pace bowling, slanting it across the batsman. Thomas gets off the mark with a quick single into the off side, two from the over and India have turned up the heat in Chennai.

Harbhajan is on-song, getting bounce and drift and causing a problem to Sarwan and Thomas with almost every ball. He appeals for lbw against Sarwan from the last ball of the over, but it pitched outside leg stump.

From Gavin, Kuala Lumpur, in the TMS inbox: "The quarter-final fixtures are getting clearer but how are the semis worked out, Stevo? Draw from a hat? If you don’t post this I’ll know you have as much idea as me, I can’t find the answer anywhere!"

Um... ah... er... hey, look over there... *runs away*

Darren Sammy is the new man at the crease, he needs to play a captain's innings for his team. Yuvraj beats his attempted drive and then Sammy gets off the mark with a single on the back foot into the leg side. India were 188-3 at the same stage of their innings.

Andre Russell is the new man and unless he sticks around with Sarwan for a little while this could all be over very quickly. Three off the over and a kamikaze, inexplicable run out.

Sulieman Benn has a swing and a miss from Munaf Patel, gets nowhere near it really. West Indies are about 12-5 from the last seven overs, incredible collapse. Three from the over and Sarwan has a heck of a one-man task now.

West Indies take the batting powerplay, guess they haven't got much choice. Sarwan chances his arm and batters Harbhajan over midwicket, before taking a single to put Benn back on strike. He misses one that gets Harbhajan excited about a potential bat-pad, before one from a length rears up and hits Benn's helmet. He takes it off and inspects, before calmly putting it back on.

Darren, Bristol, TMS inbox: "Stevo, I'm confused. Do India want to win or lose this match now? Questionable tactics for 30 or so overs, now they seem as though they're interested. It's madness I tell you, madness!"

From Daniel, Watford, in the TMS inbox: "Re. Gavin in KL not being able to find the SF line up - the ICC web site has a handy 56 page rule book which gives the SF as follows: Winner (Pakistan v B4) v Winner (Australia v B2), Winner (Sri Lanka v B3) v Winner (NZ v SA). Err...obviously it doesn't say exactly that - I've filled in Group A."

Devendra Bishoo is in now, it's all a bit too late for West Indies, who have collapsed dramatically and disappointingly. Ashwin is back, seems like years since he bowled, and there are only three off the over. Windies need 87 from 54 balls. Which ain't happening.

Last man in is Ravi Rampaul, who bowled superbly for West Indies earlier today. Bishoo cuts high to third man for a one-bounce four, lovely stroke from the talented leggie. He digs out a Zaheer yorker, good lad. Token add: they need 83 from 48 balls.

West Indies are all out for 188, India win by 80 runs.

India's Zaheer Khan (3-26): "We knew it would be difficult with the new ball, but when it was old the ball wasn't coming on to the bat and started swinging a bit and we knew we could get back into the game. I knew when I came back it was important we took a wicket and we did well as a bowling attack, which is key ahead of the quarter-final. Really looking forward to Australia."

Wednesday: Pakistan v West Indies
Thursday: Australia v India
Friday: South Africa v New Zealand
Saturday: Sri Lanka v England

West Indies captain Darren Sammy: "We are in this tournament, but we have to tighten up and tighten up very quickly. We have to take our A-game to Pakistan, we know that. Our bowling is holding up and that augers well, Ravi was superb, but the batting is a concern. We're in the knockout stage and that was our aim."

India captain MS Dhoni: "The whole 50 overs is important - if you're batting you have to finish it off well, and the same when bowling, it's not just the first five or 10 overs that count. The last 10 overs of our innings is a concern, but in the quarters hopefully you will see us at our best. Australia are a very good side, they play good cricket and are expressive on the field, but it's not about them, it's about us and what we do."

Man of the match Yuvraj Singh: "I was hitting it in the middle of the bat straight away today and it felt good. I was struggling with my stomach this morning and got cramps during the innings, but I wanted to stay out there as long as possible."

South Africa/New Zealand v Sri Lanka/England

Pakistan/West Indies v Australia/India

If England beat Sri Lanka, they would stay in Colombo for their semi-final.

From Ken Williams, TMS inbox: "That makes the semi-finalists the three from the sub-continent plus South Africa. India will beat Aus, Pakistan will beat a disappointing WI, Sri Lanka will smash England, an South Africa will romp home against the Kiwis."

On that note of negativity from our Ken, it's time to bail. We didn't get our 100th 100 from Sachin, or even a decent run chase, but at least we know the quarter-final line-up, a month into the tournament. Ben Dirs will be in the chair on Wednesday for Pakistan v West Indies, so join him then. Ciao.
