Phehlukwayo is on for his second over and is met with an in-form Morgan smacking him away for four over wide mid-off.

A couple of singles makes it six from the over.

Dwaine Pretorius remains in the attack - he'd be able to bowl 10 straight overs at his pace.

In fairness, he's kept it tight and England have found it tough to get him away.

Hang on - is this another drop? It's a very, very tough caught and bowled chance low to his right off Morgan. But they all count.

Morgan tucks the final ball into leg for a single.

Andile Phehlukwayo is into the attack and it's a good, accurate start from the 21-year-old.

He gets a maiden - the only run from the over coming as a leg bye.

You feel England have not capitalised on the military medium pace of Dwaine Pretorius so far.

He even did for Alex Hales earlier, which you can watch below if you missed it earlier...

Pretorius is interested as he raps Ben Stokes on the pads, but the lbw shout is turned down.

Sounded like bat but looked like it hit the front pad followed by the back pad on replay.

It's given as run but did indeed just hit the pads.

Missing down leg though. Stokes survives again.

Neil Virani: If someone manages to hold a catch of Maharaj, he's fully entitled to a Tahir-style lap of the ground

Poor old Maharaj - he's causing the left-handers grief because of the drift he's getting. It's almost like facing gentle away-swing. Ben Stokes can't adjust.

Impressive stuff from Maharaj on debut, deceiving the England batsman with some fine drift.

He's gone for just over six an over but really should've had a wicket or two to go with it.

South Africa go up for an lbw shout against Eoin Morgan but the England skipper got a firm edge on it first - umpire Rob Bailey getting that one spot on.

I still have no idea how Ben Stokes is still at the crease.

Chaos followed by relative calm as England pick up five form Pretorius' fifth over.

How much will South Africa rue dropping Stokes?

Dropped catches have been a theme today...

The drift is playing havoc with Stokes, he just can't get his head around it.

Somehow Stokes survives. Somehow England get seven off the over.

Stokes even ended up edging three straight balls, but the third went nowhere near a South Africa fielder to drop as he picked up two.

And breathe...

Oh this is ridiculous, Ben Stokes has been dropped twice in two balls.

This time it's keeper Quinton de Kock as Stokes' outside edge smacks into his thigh.

That was a sharp chance, Amla's drop was inexplicable.

That's regulation, truly appalling slip fielding. He's not even got a hand on it.

Ben Stokes' first ball - he edges Maharaj and it goes straight through Hashim Amla for four.

Lucky, lucky man.

Ben Stokes is the new man in and tests out that troublesome knee as Morgan takes a speedy single.

Could've been close but it was an atrocious throw that nearly goes for overthrows.

England need one of these two to really kick on and get a big score - Joe Root looked set for a decent day but was removed in the worst way.

That's very unfortunate. I don't think Morgan was trying to drive it as straight as he did. If a fielding team can get the opposition's best player out in that way, you know it's your day.
