In the past 12 months, England have fielded 25 different players.

Reckon you can name them all? Have a go...

Vihari gets one of his off-breaks to skid on to Keaton Jennings, who jabs his bat down to stop his stumps from being rearranged.

Jennings shovels a couple of drives in the direction of a few fielders, and Vihari concedes just one run from his first over. Time for drinks.

Hello. Debutant Hanuma Vihari, picked primarily as a batsman, is on to bowl. He has 19 first-class wickets under his belt.

We've just watched a clip of that run out and it is as odd as it sounds. Jonathan Trott said at the time that they left Cook to "stew" for a little bit afterwards...

Back at The Oval, Keaton Jennings gets beaten by a lovely bit of swing bowling from Jasprit Bumrah, but the batsman has the last laugh as he tickles a leggy delivery down to fine leg for his first four of the morning.

Perhaps that hastened Kevin Pietersen's departure from the England set-up.

Alastair Cook has only been run out once in Tests - this is his 290th innings.

It was against India in the third Test at Eden Gardens in 2012. And it was a bizarre run out - Cook held his bat out of the way of an incoming throw and it hit the stumps.

He was on 190 at the time, though. And he was batting with Kevin Pietersen.

A cry of "catch!" from the slips as Alastair Cook stretches to reach a fuller delivery from Ishant Sharma. There's a bit of extra bounce, the ball kissing the outside edge of Cook's bat, but it bounces before the man at backward point can get close to it.

That was like Joe Root at Southampton - Alastair Cook was dawdling and would've been gone if that had hit the stumps. He didn't dive in.

David Gower is currently giving the television viewers an architectural analysis of the London skyline.

Back on the pitch, Keaton Jennings plays out five dot balls before calling Alastair Cook through for a relatively speedy single. In fact, Cook was struggling to make his ground, there. He was helped by the fact that the throw from the cover fielder was well wide of the stumps.

Keaton Jennings has not even changed his helmet. Usually the batsmen do but that hit him on the grille rather than flush on the lid.

Ooft! Keaton Jennings ducks into a short ball from Ishant Sharma and the ball clangs off the grille of his helmet. He jogs through for a bye and then instantly takes his helmet off to check it.

He seems to be okay, prodding around a bit at the grille before giving Cook a thumbs up. Just one from the over.

Cook has looked very smooth so far.

Cook's highest score of the series, incidentally, is the 29 he made in the first innings at Nottingham.

He opts to defend his way through the rest of the Bumrah over.

This has been Cook's best start of the series.

Shot! Jasprit Bumrah offers Alastair Cook some width, and Cook leans back and cuts it heartily away to the boundary.

And four more! A bit of a heart in mouth moment as Cook pulls a short ball, but he's nailed it. The ball whizzes past the fielder at square leg and races away for another boundary.

Keaton Jennings mimes the ball swinging away as Ishant's latest delivery zips through to the keeper.

Jennings is stoic in defence, and that'll be another maiden.

Every ground has things that journalists like and dislike. For me, this is a big tick for The Oval. Uniquely for an English Test ground, there is an outside section of the press box.

An awkward push down the ground from Keaton Jennings brings him a single, before Alastair Cook sends a back foot punch through the flock of pigeons that has gathered on the square.

They all flap away unharmed, and Jennings unfurls another little push for one to end the over.

Now that's my kind of niche stat.
