Suryakumar c de Kock b Shamsi 22 (Ind 286-5)
Suryakumar Yadav is on his way.
The pace of the delivery has done for SKY as he's through the reverse sweep and it flicks off the glove.

Suryakumar is pretty much halfway off now.
Suryakumar Yadav has gloved one reverse sweeping Tabraiz Shamsi.
The umpires are just going to check to see if it has carried to Quinton de Kock.
South Africa look confident.
Suryakumar Yadav is motoring now. He has 22 off 13 balls.
A brilliant late cut, laser-like, off Tabraiz Shamsi brings him four more.
Here's how KL Rahul was dismissed a little while ago.

Shamsi has been expensive, he replaced Gerald Coetzee who is inexperienced but they might wonder could have been less expensive.
A miscued drive from Virat Kohli off Tabraiz Shamsi takes him into the nineties.

India were 91-1 after the powerplay, we were talk about them getting 360, joking about them getting 400. But I do think anything about 295 is going to be difficult for South Africa, not just because of the numbers on the board, but because of what goes on in the mind, knowing their history with chasing.

He's such an amazing timer of the ball, Suryakumar. When the ball's coming onto the bat, he's almost unstoppable.
Another single gets Virat Kohli on to 89.
Suryakumar Yadav, meanwhile, drills Marco Jansen straight down the ground for four.
He makes it back-to-back boundaries by flaying the South Africa seamer's final ball through long-off with a flamboyant slash through mid-off.
Image source, Getty ImagesA bit of a gift from Marco Jansen at this stage as he's too straight and short to Virat Kohli who whips it to the boundary at deep long-on.
He follows it with a couple or runs through third. Kohli is unbeaten on 88.
"Kohli, Kohli, Kohli" reverberates around Eden Gardens. It'll be fever pitch when he gets within a boundary hit of three figures.

South Africa's tactics are sound. Get Kohli into the 90s and watch them turn down singles until he is out for 95.

This is where we're going to see the sub-themes play out. We've seen previously India players support batters reach their hundreds, but Kohli doesn't have much time left.
Tabraiz Shamsi flummoxes Suryakumar Yadav, who pushes forward with hard hands and clips the ball up.
It offers Shamsi a tough caught-and-bowled chance. The South Africa spinner dives forward but is unable to get his hands under the ball.
Suryakumar gets down low to powerfully sweep Shamsi's final delivery for four.

South Africa's death bowling hasn't been great, they haven't really got an assigned death bowler. But have India got the big hitters?
That brings the mercurial Suryakumar Yadav to the crease, and he cuts the final ball of Marco Jansen's over to the boundary through point.
A blemish on what was otherwise a superb over from the South Africa left-arm seamer.

That's the answer to the questions that's been posed - when are India going to up the tempo. That seemed to be the signal. Marco Jansen gets some joy after what's been a really difficult day for him.
KL Rahul c van der Dussen b Jansen 8 (Ind 249-4)
KL Rahul struggled to get going on this pitch and having chewed up 17 balls for eight runs he holes out.
He is unable to quite time a whip off his legs to Marco Jansen and skies it towards deep square leg.
Rassie van der Dussen sprints in and is able to slide on his knees to claim a brilliant catch for South Africa.

The number of extras has been a concern for South Africa. In their defeat to the Netherlands, extras was the Dutch top scorer until the seventh wicket partnership.
