Liam Livingstone had a mad moment - there was no communication. He just went for it.
Livingstone run out 16 (Eng 166-6)
What on earth was that?! Liam Livingstone's had a moment of real horror there. A comfortable single, Dawson never signalled for the second run but Livingstone had committed. He was stranded at the wrong end as the bails came off.
Another good, full delivery from Andile Phehlukwayo and again, Liam Dawson can only crack it in the direction of a fielder.

Everything is moving back into South Africa's favour now. It's exciting stuff.
Liam Livingstone is on strike. AB De Villiers has brought his field up and Livingstone can't beat it, smashing a slower ball up to cover.
Target 175
Andile Phehlukwayo will bowl the final over, and he twirls down a yorker that Liam Dawson cracks away for a single.

Liam Livingstone... what have you got?
Liam Dawson is the new man and he clubs away a single to get off strike. England need 12 from the final over to win!

This is what we wanted to see - the youngsters are being tested now. They are having to handle the pressure. There's a contest on. Who will hold their nerve?
Morgan c De Villiers b Paterson 6 (Eng 162-5)
Gone! AB de Villiers has caught a ball that he didn't see coming! Morgan slapped a full delivery, trying to go over the field, and AB lost it as it came flying towards him. He stuck his hands out almost on instinct and ended up catching it snugly. I didn't see this coming a few overs ago.
There's four of them! It's just a touch wide from Dane Paterson and Morgan clatters it through the covers for four.
That's an ouch for the bat, rather than a player - Dane Paterson has just destroyed Liam Livingstone's bat with a fine yorker. The ball came fizzing down and it's snapped the bottom of the bat off! England manage to snaffle a single though as the fresh bats come out. 17 from 9 balls needed.
Liam Livingstone lines up a good length delivery from Dane Paterson, has a big ol' slog at it, and misses completely. That's a wide though from the bowler, trying to keep Livingstone under pressure. And he's been wided again by Michael Gough! Paterson looks thrilled while AB De Villiers has a massive grin on his face. That's not a wide.
England need 21 runs from the final 12 deliveries. It's Eoin Morgan and Liam Livingstone at the crease. You'd still have England as the favourites but South Africa have stepped it up here...

The game has become a lot closer than when Roy and Bairstow were at the crease and England were cruising.
Target 175
Eoin Morgan is at the crease, but he has to stand at the other end and watch as Liam Livingstone misses an attempted scoop shot. That is an awful looking thing when it goes wrong, and he wasn't far off edging that to the keeper.

South Africa have hustled Liam Livingstone with some good pace and fielding. We might be set for an exciting finish.
Buttler b Phehlukwayo 10 (Eng 153-4)
That is a brilliant yorker from Andile Phehlukwayo! There's an audible groan as Buttler departs, the bails dislodged by a superb bit of bowling from the South Africa seamer. What a delivery.
Andile Phehlukwayo is back, and his first delivery gets swatted away by Liam Livingstone for four! The same man then clobbers a straight drive beyond Phehlukwayo and Farhaan Behardien tidies up.

Daniel Potter: Sadly it's out - Roy has moved across the wicket to cover the stumps, obstructing the route for a run-out. Ball doesn't need to hit.
Sam Taylor: That's an absolute shocker of a decision. Like with Stokes v Australia. in slow motion looks intentional. No way at full speed.
