Jonny Bairstow keeps victory over South Africa in perspective

This happened while Roy was rushing back after his partner Liam Livingston refused a run, as he turned and ran across the pitch and the ball struck his boot as he made his way back. The third umpire had a long hard look at the replays and in the end gave the decision in South Africa's favour.

Durban-born Roy, dropped from England's Champions Trophy semi-final loss to Pakistan after a run of low scores, was in superb form.

Andile Phehlukwayo held his nerve in a dramatic final over which ended with England three runs short after Liam Dawson couldn't hit the four required from the last delivery of the match in the growing gloom.

De Villiers made a quick 46 runs from only 20 balls, despite not timing the ball particularly well, and after he holed out off David Willey (1-29), the innings lost momentum.

Curran, the son of the late former Zimbabwe worldwide Kevin Curran, struck with just his second ball in global cricket when Reeza Hendricks bottom-edged a pull into his stumps.

The circumstances described in the new playing condition (i.e. a batsman significantly changing his direction of running without probable cause ) are only one example of an action which will qualify as wilfully obstructing the field.

He perished from the very next ball, however, lofting the same bowler to Eoin Morgan to depart for 46 and leave South Africa on 127-5.

Yes, this is not a full strength squad, but something doesn't seem to be quite right about South Africa at the moment, and it will be up to De Villiers to show that isn't the case.

The third and deciding match between England and South Africa will be played at Cardiff on Sunday.

England's second NatWest IT20 against South Africa went down to the wire as the visitors won a thrilling match by just three runs.

Curran had Morris caught off a slower ball and the 22-year-old then bowled Phehlukwayo for a golden duck with an excellent yorker.

Prior to the series, Morgan told the European Central Bank website: "It's an exciting time - we have rested players and a lot of new guys have come in".

But Morgan insisted England had only themselves to blame, saying: "We didn't deserve to win because we didn't capitalise on the start we had". "It's not an easy decision and it's never nice to get out like that", he said.

Kuhn also tops the charts on the first-class component of South Africa A's tour with 320 runs at 106.66 and two centuries - one of them an effort of 200 not out against Hampshire.

"We go to Taunton and like all South Africans we always fight our way back so I'm expecting a really good performance in the next one".

"But I don't think anything can prepare you for when you actually get out there - the nerves, the adrenaline".
