Root stumped on 149 off a no-ball; also dropped on 16
Skipper shares in big stands with Moeen (61*) & Stokes (56)
Three wickets for Philander
England won toss; first of four-match series
Spin for the first time, the left-armers of Keshav Maharaj. He's at the Pavilion End, which means he has turn the ball up the slope. Bairstow doesn't seem keen to want to let him settle. A drive, a sweep, but no decent contact. No real turn, but tidy stuff.

Rabada is quite hard on himself, he expects a lot and is determined to put in big performances.
Root 26, Bairstow 8
That's nice from Root. When Rabada gets too full and leggy, the new skipper rolls his wrists to take four up the hill to the square leg fence. Rabada is bowling in the high 80s, but he hasn't had the happiest of mornings - both sides of the wicket. We've got about 25 minutes to go until lunch.

It's not comfortable for the England batsmen, this trio of seamers are high class. Philander you always know will get something out of the new ball at a consistent length. Morkel gets bounce and Rabada, though not at his best yet, always has a tremendous ball in him.
Another edge from Root, this time bouncing before the slips. Extra bounce from Morkel, past the attempted cut of Jonny Bairstow. It feels like every delivery is full of danger for the England batsmen, every propulsion from a Protea pregnant with the potential for peril. Don't take your eyes of it.

England always feel the best way to combat losing a few wickets is to attack but just survive! Just try to see them off. They've only got four bowlers.
Eng 64-3

It's a pretty loose drive from the England skip, pushing his hands through a wide one from Kagiso Rabada. Duminy, at gully, has to either catch it or wear it. His fingertips deflect it to the boundary. He's dropped it, but at least he didn't take leather to the face.

The Lord's equivalent of the German towel-on-sunlounger: picnic blankets and hampers laid out in the Coronation Gardens hours before their scheduled use.
Looking at that stat, would it save some time if England just started every innings at 50-3? Morne Morkel is galloping in, knees raised so high to be almost touching his chin. He gets one to climb at Bairstow, nipping up the slope, grinning at the batsman as it goes past the outside edge. Bairstow responds with a cut for four.

Over the last three years, in 64 innings, England have lost their third wicket at 55 or lower 23 times.
England at least have two right-handers at the crease, so Morkel's main source of prey is ended for now. Then again, Stokes and Moeen are in next. Bairstow immediately looks at home, angling Rabada along the ground to third man for four.

His head goes nowhere, his feet go nowhere, it's almost like French cricket. The worry for many with Gary at number three is that all England's top three can be restricted by a good bowling attack.
Morkel 5-1-21-1
Is the debacle over the reviews going to overshadow the fact that England's top order is once again in ruins? I know it's only the first Test of the summer, but 50-3 has been the norm for what seems like living memory. Ballance was pushed back, then suckered by the full ball. Jonny Bairstow is once again asked to do the recovery work.

That's a promising innings that has come to an end in the worst possible way, his front foot was barely an inch ahead of the popping crease. Just a little bit of movement but there is a real silence in the crowd. Can you see Ballance batting at three in Australia against all their fast bowlers?
Ballance lbw Morkel 20 (Eng 49-3)
What is going on out there? England might need some reviewing classes to go with extra batting practice. It couldn't have been anything but out. Morne Morkel round the wicket, full and straight. We said that Gary Ballance was playing around his front pad and that's what has happened here. It would have hit middle and leg halfway up. England in all sorts of bother.
Eng 49-3
England didn't review when Jennings shouldn't have been given lbw. Now they are reviewing when Gary Ballance looks stone dead.

Members don’t even have to wear ties in the House of Commons now, so why do they need to do so at Lord’s.

Before the game, there were concerns play might be disrupted by rampaging elephants since the ground is next to an elephant shelter. Zimbabwe have everything crossed...
Full scorecard of that one is here.
Missed the first hour? It's been busy.

Rabada hasn't quite got it right, he has bowled a bit too wide to Joe Root. Joe had a bit of fortune with that one that went over the fielder's head. South Africa will be delighted with their start, to get Cook who has been in such good form for Essex. But this pair have settled down and Ballance has looked good. People say Root looks nervous but I just think he has batted the way he normally bats.
