Rishabh Pant is eyeing a little bit of history here. No India batsman has ever made a hundred in each innings of a Test against England.
There is turn out there for Leach though, as he's able to bowl five dot balls to Pant for the remainder of the over.
Still can't get over that shot. How does he do it?!

You're not exaggerating, it was about four feet outside off. That is an incredible, incredible shot.
Daniel Norcross
BBC Test Match Special
Wow, he's taken that from about four feet outside off stump!
Ohhhh Jack Leach. He must just want to cry whenever he sees Rishabh Pant.
He bowls his first ball wide of off stump and somehow, in the most incredible way, Pant takes a step and is able to slog sweep it behind square leg for four, falling over in the process.
That is just hilariously bonkers.

Jack Leach, good. I like to see this.

That is James Anderson's 100th Test catch.
Ah. Ravindra Jadeja and Rishabh Pant join forces again.
Just what England need when they trail by 322.
Jadeja threads Potts perfectly through second and third slip for a boundary.

If ever there was a sucker punch, we've just seen it. England have bowled a few short balls to Iyer this morning and he's played a few pull shots but never looked very convincing.
Simon Mann

Would you believe it? The plan has worked. It feels like quite a soft dismissal. Iyer playing into England's hands.
Iyer c Anderson b Potts 19 (Ind 190-5)
He makes things happen!
It's another soft dismissal as Iyer pulls a short ball straight into the hands of Anderson at mid-wicket.
England were testing him with some short stuff as he looked so comfortable driving on the front foot, and the plan works!

England are leaking runs, India are ticking along very nicely and the only time Pant has looked in trouble is when he's tried to be more inventive.
Lead by 318
The game is drifting further and further out of England's reach.
Right now you'd say 318 is chase-able. But there are still basically two days left and six India wickets to take.
They've got one this morning but need to take those remaining ones pretty quickly.

Pant is at it again. It's been relatively conservative by his standards but it's been effective, he's stroked it around nicely.
A deft touch down to the fine leg boundary brings Rishabh Pant another half-century.
It's not been his usual extravagance, but an important knock. Now he's reached fifty, we may see a bit more of his flamboyancy.

Andrew Gell: Crawley and Lees both have eternity rings. It means while you wear one no matter how poor you are you will open for eternity.
Andrew that is absolutely brutal.

That was more of a half-volley but Potts has had his success by going that bit fuller so you can't really blame him.
Lead by 310
The only thing Potts is making happen at the moment is boundaries.
That's harsh because he as so good yesterday but he's just been a bit full to Shreyas Iyer, who's been able to thread two lovely cover drives away for four.
Simon Mann

An outrageous shot from Pant. We've seen lots of players try outrageous shots this summer so we really shouldn't be surprised.
Here we go!
Rishabh Pant attempts a reverse scoop/ramp/pull thing but completely misses. It takes Sam Billings totally by surprise (fair) and he's just able to stick out a hand to stop it.
The fun starts now, I think!
