A no-ball after Tabraiz Shamsi oversteps, and Virat Kohli attempts to hit it into next week but is unable to make contact with the ball.
It's followed by three wides and a couple of runs off the bat. Curious over from the left-arm wrist spin.
Those old-fashioned pylon floodlights are now beaming down at Eden Gardens. Brutalist beauty.
India might have been eyeing up 400 after making such a blistering start but South Africa's bowlers have been quietly chipping away.
Marco Jansen with another solid over as he denies both KL Rahul and Virat Kohli any width. Four singles off the over.

Your team comes first, but I think any player would be lying if they said if they didn't look forward to milestones or just nervous approaching them.

A tight over from Kagiso Rabada as he stymies India's batters, mixing up yorkers with some testing balls back of a length. Just three singles off the over.

South Africa's record chasing in World Cups has been pretty poor. Their highest in the tournament is against India, that's 300 in Nagpur in 2011.
Lungi Ngidi scoops himself off the turf to finish the over.
He gives Virat Kohli a bit of trouble with a yorker from his final delivery which prompts the India batter to jam his bat down to save his toes, and protect his stumps.

While we wait for Lungi Ngidi to get back on his feet... Here's how Shreyas Iyer was dismissed a few moments ago.

It was a classic shot from Kohli, right back at the bowler. He stuck his foot out instinctively, the ball came off the top of the foot.

Ngidi then crumples on the pitch in a little bit of pain after his follow through.

Now is the time to bring Jansen back. He's struggled today and I wouldn't want him to bowl four of the last ten with the pressure on.
Kagiso Rabada, who has been fairly tight so far, strays on to Virat Kohli's pads with the first ball of his seventh over and the India batter effortlessly
That's meat and drink for a player of Kohli's class. He now has 73 off 88 balls.
KL Rahul is the new batter for India.

It's Virat Kohli's birthday today, by the way. He has turned 35. A century here would the icing on the cake for him.
Are there any other sportsmen or women who have done something brilliant on their birthday?

You can see the reasoning why Iyer has lost his wicket. Continually trying to up the ante, put the pressure on South Africa. Kohli is there to drop anchor, ensure he's there at the end.
Iyer c Markram b Ngidi 77 (Ind 227-3)
Shreyas Iyer has skied a couple off South Africa's bowlers attempting to go down the ground but this time his luck runs out.
Lungi Ngidi rolls his fingers over the ball and Shreyas Iyer's eyes light up, but he has not quite timed it.
Aiden Markram is stationed at deep mid-on and has to wait an age before he pouches the catch.
A partnership worth 134 with Virat Kohli.

Another bowling change from Temba Bavuma as Kagiso Rabada is summoned.
Shreyas Iyer pings his penultimate delivery flat towards long on where Marco Jansen is fielding.
The crowd falls deathly silent thinking Jansen has held the catch but the South African has only managed to stop it on the half-volley.

You have to get a bit funky and mix up your bowlers on a pitch like this.

Virat Kohli advances to Lungi Ngidi and with a powerful wristy flick, clips his first ball to the boundary for four. Clinical shot.
A few balls later Kohli dances down the track to a slower ball from Ngidi, looking to go down town, but it is a fresh air shot as he is beaten on the outside edge.
Kohli curses himself before pinching the strike off the penultimate ball of the over.
