It's been a good start by England. To restrict South Africa and take three wickets allows them to continue to be aggressive.
Here is Wood's second wicket. Told you it was quick...
Behardien gets under way with a smart steer from a Jordan short ball that skips away to the rope at third man. Jordan keeps the variety coming and it serves him well for the rest of the over.
Here's Mark Wood's first wicket - David Willey leaping like a salmon at mid-wicket.

South Africa are 7-3 off the first ball of overs today.
Now it is AB who has to duck and weave to avoid a Wood short ball. Brilliant over. One wicket and one run off it.

You could hear the edge from up here in the commentary box. Mark Wood has done him for pace. He brings X-Factor to this team.
This is quicker! Welcome to the crease Farhaan Behardien. Wood goes short and the batsmen has to take evasive action to fend him off. Heat in the heat.
Miller c Buttler b Wood 9 (SA 32-3)
This is quick. Wood tears in and gets the first ball of the over (always the first!) to skid through at pace and fire through Miller, but not before taking an edge that carries to Buttler.
SA need a partnership.
Chris Jordan didn't get the memo. His first ball fails to get a wicket as De Villiers prods another single to off.
It is a good over from the seamer, though. He varies his pace, keeping AB in check with some clever slower balls, one as pedestrian as 65mph. He tarnishes it slightly with a full final ball in the slot that De Villiers dispatches for four.

De Villiers and Miller look set, they are playing proper shots and hitting through the line. It's such a good pitch.

Despite the loss of two early wickets, these two - AB de Villiers and David Miller - look in good shape.
De Villiers 14, Miller 8
Miller isn't messing about. He walks towards his first ball from Willey and plants the ball into the stand behind the bowler. Dismissive.
Willey responds superbly, though. Only two more runs from the over.

That's the genius of AB de Villiers - he threaded the ball through the off side. Pure class.
Three slips in to greet David Miller, who we know can whack a big ball. He gets away with a single.
AB finds the middle of his bat with a beautiful back-foot drive through cover for the first boundary. He ends the over with another luscious back-foot shot for four, this time through extra. Form is temporary...

That was all about the bounce. Mark Wood banged it up and the batsman couldn't control it because of the pace the bowler gets. And what a fantastic leap from David Willey.
Hendricks c Willey b Wood 3 (SA 7-2)
Anything Willey can do, Wood can do... er... the same. THe Durham pace bowler digs one in first ball and Reeza Hendricks whips it straight to Willey at mid-wicket. England are on fire.

That's the third England time have taken a wicket with the first ball of a T20 international. The other two were Jade Dernbach v West Indies in 2014 and Steven Finn against South Africa in 2012.
