Ex-England batsman on BBC Test Match Special
"It's a fine innings in what might finish up to be a losing cause, but it might still give England a sniff of a chance."
Eng 216-7
Image source, Rex FeaturesAnd there it is! Root clips a single off his legs to get to three figures - it's been a terrific effort from the golden boy, he's held this innings together. And then some very welcome biff from Rashid, heaving Wiese over mid-on for four. He's started at a decent lick...
That will do nicely! Wiese overpitches a fraction and Rashid lofts a glorious inside-out drive over the covers for a one-bounce four. Superb. A single brings Root on strike on 99...
So, a significant role to play for Adil Rashid at the end of this innings. He needs to bat with a bit of tempo - he can't afford to waste too many deliveries getting himself in. He's off the mark immediately with a flick into the leg side, but England need to start finding the boundary again pronto.

"That was really short. A batsman can't control those sort of shots, up high."
Woakes c De Kock b Rabada 33 (Eng 203-7)
Image source, Rex FeaturesOh, crumbs. That could be a big wicket. Woakes trying to pull a ball that gets big on him and getting a faint glove through to Quinton de Kock. Kagiso Rabada does the trick yet again.
Eng 202-6
So we enter the final Powerplay. England will be thinking 10 an over from here, I reckon. Woakes shows the intent but not the execution, heaving David Wiese over the top but only getting the ball to land just short of long-on. Root brings up the 200 with a single through the covers, but singles are all the change England are getting out of that over.
Ten overs to go for South Africa and they are 173-3 chasing 263 to beat England in Centurion and level the one-day series.
Marizanne Kapp and Lizelle Lee have put on a rapid half-century stand but the hosts have a lot to do, even with plenty of wickets in hand.

Phewf. Root has got a feather of an inside edge on that and he lives to fight another day on 95.

"I think this looks a good shout."
Tahir hits Root on the back pad and the finger goes up, but Root reviews straight away. Has he hit it?

Mr H: never mind dolly the sheep, clone Joe Root!
Fenners: Bit worrying that Woakes is finding batting easy, imagine what Amla / de Kock will do!
England not quite finding the boundary rope as easy to locate now that Wiese and Morris are out of the attack. Kyle Abbott fires down five frustrating deliveries, but off the last ball, Joe Root cashes in - just turned delicately round the corner past short fine leg for four. Much needed.

Richard Sanderson: If Root and Woakes can stay in until the end of the innings England might still be able to post a respectable total.
Michael Short: England must open with Root, then play nos. 2-11 with Root by himself. The only England player who knows what he is doing!
Paul: Joe Root once again showing that he's the class act when it comes to batting for the conditions.
Imran Tahir back to try and break this partnership. He can't do that, but he is exerting a vice-like grip over the run rate at the moment - just three from another suffocating over.

Ooh, this is good from Root - decent length delivery from Abbott but Root somehow manufactures a bit of length and smites it through mid-on for four. And that's even better - sashaying down the track and belting Abbott into the stands. That made a heck of a crack off the bat. This game isn't over, folks...
