Short from Mortaza, the roar from the India fans makes one anticipate another boundary, though Dhawan doesn't quite get hold of it and just lobs it for two over mid-wicket. The same fielder, Nasir Hossain, is kept busy as Dhawan knocks it past him, Nasir gives chase and pulls out the full belly-flop dive with both legs in the air... but just fails to stop it knocking into the rope. Four signalled.

"It is still less than half full, but there are more people turning up all the time. We have people in wigs, pirate hats, a couple of bands are playing. There's a tremendous atmosphere and an excitement and celebration for cricket for every shot. It is just an absolute passion for the game."

Nasir, bowling round the wicket with a rather round-arm action, isn't finding much joy against the left-handed Dhawan, who adds a single to his score, while Rohit advances a couple of strides down the pitch and lofts the off-spinner for four over mid-off. The Indian fans are loving this, as well they might.

"The ball is coming on nicely and that's always a good sign when you just push one and it races away for four. India have no excuses and will hope to make life difficult for Bangladesh."

Mortaza to continue, but it's business as usual for India as Dhawan crashes another four through cover point, and helps himself to an easy two before a single to third man takes him to 13 from 16 balls. Rohit, who's had rather more of the strike, has 18 from 26.

Bibhash Dash: Having just four hours of sleep is always made worth it by such a start. 300-plus the minimum.

Bangladesh make an early switch to spin, in the shape of off-spinner Nasir Hossain. Keeper Mushfiqur Rahim is keeping wicket in a pair of bright orange reflective sunglasses - more surprisingly in these modern times (given the career-ending eye injury SA's Mark Boucher suffered a couple of years ago), he's not wearing a helmet. Dhawan easily knocks a single to the man back at long-off, Rohit dabs one past the diving bowler, and India look in no trouble at this stage.

"It feels like there are 200,000 people out there, but there is probably only 20,000 here. It is a great atmosphere. I can see the Bangladeshi band. They have two or three drums down there but they will need some stamina to keep this noise up."

Mortaza moves his second slip to a short point position - remember, you're obliged to have two static "catchers" for the first 10 overs. Not a position for the faint-hearted. Dhawan rotates the strike with a leg bye, which umpire Dar signals with the minimum of fuss, as compared to the flamboyance of some of his umpiring colleagues. Then there's a mix-up as Rohit pushes for a quick single, non-striker Dhawan slips over but Tamim Iqbal's throw goes to the non-striker's end when it might have left Dhawan struggling if it had gone to the other end. Dhawan taps-and-runs one to nick the strike.

"In one-day cricket Bangladesh are improving, they have quite a bit of experience and they are understanding the game better. But the one thing that does disappoint me with Bangladesh cricket is in the Test matches where they have not seemed to have improved."

Taskin to continue - I wonder how long Bangladesh will keep going with these two, or if we'll see the slingy action of Rubel Hossain, who tormented England in Adelaide, soon. No joy for the teenager as Taskin tries a shorter delivery and Rohit Sharma swats it backward of square leg for his third four, while he helps himself to another two off his legs.

"A score of 400 could be on for India today. Has any team ever made 400 in a World Cup quarter-final before?"

Not much in it for the bowlers today so far - even when Mortaza finds the edge of Rohit's bat, the ball bounces in front of second slip and scuttles down to third man for a single.

"It is as if India are playing at home here. Three strikes, two off the bat, one flicking the pads, have already brought boundaries."

The deluge of fours continues - Rohit taps another four back past the bowler. The bottom tier of the MCG doesn't have many spare seats left - I heard earlier they're expecting at least 50,000 to have turned up in total.

Shikhar Dhawan takes guard against teenage right-arm seamer Taskin Ahmed, who'll take the other new ball from the Great Southern Stand End. (For those of you who know the MCG, this is a bit of a misnomer, as the ground is a huge, 100,000-seat amphitheatre rather than having particularly distinct stands). Taskin has two slips in, probing outside left-hander Dhawan's off stump, but he's off the mark with an effortless four through the covers from a checked drive.

Milan, London: As much as you guys want the shock. India are not England. We will not mess this up...

Mortaza, one of three front-line seamers in the Bangladesh XI, tightens up his line for much of the over - but then flights one down the leg side, Rohit tries to leg-glance it and it flicks off his thigh pad for four leg byes. Eight off the first over, keep that up and we're on for one of those 400 games...
