So, even under the "double-the-score-at-30-overs" formula, India would be disappointed with only scoring in the region of 250 - while it remains to be seen whether that lurking possibility of a rain shower, and the attendant presence of Messrs Duckworth and Lewis, would help or hinder them.

Rohit and Raina take five singles and a wide from Nasir Hossain's seventh over, and the players have earned another round of drinks.

"Very impressed with Bangladesh today. They have used the pace really well, fields have been aggressive. If anything, the game is marginally towards Bangladesh."

Young Taskin Ahmed must know - as just about everyone in world cricket does - that Suresh Raina isn't particularly comfortable against the short ball, so tests him with a bouncer which he helps down to fine leg for a single.

India are picking out the fielders a lot today - which, I guess, should be to the credit of the fielders, and the captain, as well as the bowler. Rohit pushes a single to third man, then Raina gets a thick edge... past the solitary slip and away for four. Moral victory to the bowler, four runs to the batsman and the flag-waving Indian fans are on their feet again.

OptaJim:, external Mushfiqur Rahim now has five stumpings to his name in Cricket World Cup history, the same as MS Dhoni, only five wicketkeepers have more.

India 126-3 from 30 overs (India won toss)

Batsmen: Rohit 57, Raina 6

Fall of wickets: 75-1 (Dhawan 30), 79-2 (Kohli 3), 115-3 (Rahane 19)

The doctor's been to have a look at Mr Dar - as has fourth umpire Paul Reiffel, who'd probably have to step in and take over - but the Pakistani official will carry on for the time being. But he's not the only one who's suffering here - India are batting as though they've been stung. Raina is off the mark with a single.

England announced their Test squad for their away series against West Indies yesterday.

"I'm pleased that Adam Lyth has been given an opportunity and I'm glad to see Jonathan Trott is back. But James Tredwell is the reserve off-spinner and I can't understand that. He had to go out on loan because he could not get in the Kent side. His strength is one-day cricket but he can't get in the team.

"Gareth Batty at Surrey has been the best off-spinner behind Graeme Swann. If you're going for experience then Gareth Batty is in form. He is the next best off-spinner in county cricket."

Shakib take a rest, possibly being saved for the powerplay, as Nasir Hossain returns, and new batsman Suresh Raina tries to help the ball away as four leg byes are signalled.

Meanwhile, there's a hold-up as umpire Aleem Dar suddenly seems to have something wrong with the back of his neck - has he been bitten by a bee or a wasp? As someone who once had to be treated for a wasp sting by the Hampshire physio during a County Championship match at Northlands Road, I can sympathise. (I was about seven years old).

"I've never seen celebrations like that. They chest-pumped and the third time they did it they ended up on their bums. You could see what Rahane was doing. He was trying to dink it over mid-off and it was a good time to get the wicket.

"India were starting to go up the gears, but the only way to restrict this type of team is to keep taking wickets."

But straight away, Bangladesh are back in it as Rahane goes for a lofted drive and is well caught at extra cover. The pendulum swings back towards the Tigers, who are scenting prey here.

And a sensational celebration - two of the Bangladesh players, Taskin and Mortaza, leap up to "chest-bump" each other, and when they try it again, they both fall over! With Mortaza's injury history, that may not be advisable...

As if reaching 50 has re-energised Rohit and taken a weight off his shoulders, he smacks Taskin for four through mid-wicket, while the singles have started to flow again for this third-wicket pair, who have now added 36 in 10 overs.

"Bangladesh have Mominul Haque on as a sub, fielding on the boundary. While he's there, bowling coach Heath Streak pops out, complete with tablet and dishes out some instructions. Is that allowed?"

That's fifty for Rohit, from 70 balls, as he carves Shakib for a couple of singles. His strike rate, around 71, is a little behind his career ODI strike rate of 81 runs per 100 balls.

In fact, he had 40 from 49 balls when the first wicket fell. Since then, he's scored 10 from 21.

"If I was Kevin Pietersen, and he desperately wants to play for England, he should just go and play county cricket and see what happens. He can't get back into the England team if he plays in the IPL and has very small chance of getting back in if he plays county cricket."

Hear that? Rain on the way in a little while, get your waterproofs ready. But Bangladesh have already poured cold water on India's fiery start, putting a dampener on the favourites. Once again, Taskin keeps Rahane in check for four dot balls before he finally beats the infield with a two to push India past 100, while the boundary drought is ended with a swipe for four though the vacant slip cordon - that's the first four since the ninth over.

"There's an 80% chance of rain between 5pm and 6pm here [06:00-07:00 GMT] so it may hit us in about an hour's time."

Ex-England batsman Kevin Pietersen yesterday said he wanted to play domestic cricket this year, in a bid to return to the national side, before national selector James Whitaker said the 34-year-old was "not part" of their plans.

"English cricket is in a pickle and it has continued in the last 24 hours. It is madness.

"You have the Test captain Alastair Cook having a pop at being left out of the World Cup and he said he would've got England to the quarter-finals. He is having a pop at James Whitaker. It is very unlike Cook, He is clearly a bit bitter and upset at not being in the World Cup. He is allowed his opinion, but you rarely hear from him like that in public.

"In the last two years he he has struggled in one-day cricket, losing six series on the trot. It is all a bit of looking after yourself at the moment in the England team."

Mortaza hustles his players round quickly between overs, Rahane pushes the ball into the covers and sets off for a run as keeper Mushfiqur races out from behind the stumps to field. Rohit is crawling towards his half-century, now on 48 from 67 balls. Plenty of energy shown by batsmen and fielders, and while talk of 400 may now be rather optimistic, I wonder what score India might settle for at this halfway stage. 300? 350?

"In case you needed reminding, the highest score made to win an ODI batting second at the MCG is 297. If Bangladesh only have to chase that many today, they will be very, very relieved."

Rubel takes a rest after taking 1-14 from six overs - in fact, he's off the field having his foot looked at. It's Taskin Ahmed back on, and even the upper tiers of the MCG are starting to fill up now - perhaps folk are coming in after finishing work for the day. Rahane takes a while to get the ball off the square - just one from the over, well bowled the teenager.
