I think it's going to take something remarkable from the Bangladesh batters. India have got more than enough runs on the board.
A good yorker to finish and another single to Virat Kohli, who acknowledges the crowd and his team-mates as he walks off the field unbeaten on 64 from 44 balls.
It's going to be a tough ask for Bangladesh, who will need 185 to win.
Another full ball is dug out by Ashwin and they scramble a single.
Virat Kohli gets back on strike and bags two more.
One ball to go...
And another four!
It's actually a very good ball from Shoriful Islam after the pie from the previous one, almost a yorker - and Ashwin somehow smashes it down the ground!

No need to get Kohli on strike if Ashwin is going to hit like that.
Get Kohli on strike?
Nah. Ravichandran Ashwin pummels six of his own over square leg.
One over to go.
It's been a tough outing for Bangladesh but can they finish well?
Oh. That's beautiful.
Six over long-on with the most graceful arc of the bat from Virat Kohli. He stands and admires it himself, and why not?!
Hold the pose.
Short, pulled, one bounce four.
Virat Kohli continues.

Bangladesh have bowled really nicely. They're having a good time and have smiles on their faces.
And he does that job.
An easy single.

The job of Ashwin now is just to get Kohli on strike as quickly as possible.
Axar c Shakib b Hasan 7 (Ind 157-6)
A much easier chance for Shakib this time.
Axar Patel looks almost like he's trying to get out, just plopping the ball straight up in the air for a simple catch at cover.
Ha, just look at the position Hardik Pandya is in when he plays this shot.
Amazing.
Oh, so close! How many times have we said that?!
Axar swings, the ball loops up towards cover where Shakib Al Hasan puts in a heroic dive but the ball just evades his fingertips.
Two overs to go then, with Virat Kohli on 50...
A gift for Axar Patel, clipped off his legs for four as Mustafizur loses his line.
Karthik run out (Shakib) 7 (Ind 150-5)
Gone!
Dinesh Karthik wanted the single, Virat Kohli not so much.
He sends him back, Karthik having to dive full stretch and is run out by a distance. There's a bit of a delay as the umpire checks whether the ball or the bowler's hands broke the stumps, but he's happy with it.
Has Dinesh Karthik been run out? Looks close, but has the bowler broken the stumps cleanly?

Kohli punches the air. He knows he's finding his form. Whoever is bowling against him will be in trouble.
