Cook and Elgar of course present a new challenge for the bowlers, as they're a left-hand right-hand combo. Not so easy for Jimmy et al to settle into that groove outside off stump. Elgar tucks a single into a gap at midwicket.

This is the fifth time opposing opening batsmen have shared the same surname in a Test. The full list:
Stuart Broad now to deliver his first over as officially the world's best bowler. That's got to put an extra pep in your step, hasn't it? In public, Broad has greeted the news with admirable modesty, but I bet in private he's been crowing all week. "Jimmy, could you pass the salt to...the world's NUMBER ONE Test bowler please?"
Anyway, I digress. Just a couple of singles off his first over.

Former South Africa wicketkeeper on BBC Test Match Special
"I don't believe in dead-rubber games. There's a long history between these sides - there's a lot of pride at stake. It's not a great feeling losing a Test match. England will want to get on the plane knowing they have won this 3-0."
As Jerusalem rings out around the ground, Jimmy Anderson makes a rather sedate start, drifting a gentle loosener onto Stephen Cook's pads. Cook gets his international career off to a rollicking start by clipping it off his legs for four. That alone will earn him at bragging rights at the Cook family Sunday lunches: father Jimmy lasted only one ball on his Test debut.
Anderson, in generous mood this morning, offers Dean Elgar a leg-side half-volley to get him started too. Another four results, and the hosts are off to a flyer.

Former South Africa wicketkeeper on BBC Test Match Special
"It will be nervous times for South Africa this morning."
So, a big day for Stephen Cook and, right on cue, there he is, out in the middle. Jimmy Anderson, well and truly revved up by those fighting words from AB de Villiers, has the shiny new ball in his hand. Let's get down to business...

"He's similar to his dad - he likes to cut and pull. He'll be nervous so it will be interesting to see how England bowl at him."
It's a big Test match for England's Alastair Cook - the skipper is 117 runs shy of becoming only the 12th batsman to reach 10,000 Test runs and the first player to do so for England.
Meanwhile, South Africa also have a Cook at the top of the order: Stephen Cook, who makes his Test debut at the ripe old age of 33. He's got a solid first-class record behind him, with 35 hundreds and an average of 41.
The latter Cook is himself the son of Jimmy Cook, the former Somerset and South Africa batsman.

Pete Hardy: England want 3-0 so have gone for Woakes as the experienced player to bring in for the injured Finn.
Joe Mannick: Absolutely gutted for Footitt! Guess England see Woakes as a like for like replacement when Anderson hangs up his boots.
After his heroics in the third Test, Stuart Broad has now officially vaulted to the top of the ICC Test bowling rankings.
The Nottinghamshire seamer now sits above India's Ravichandran Ashwin and South Africa's Dale Steyn.
Sir Ian Botham and Steve Harmison are the only other England bowlers to have been ranked number one.
The normally reserved AB de Villiers was in feisty mood at yesterday's news conference as he poured a bit of kerosene on the smouldering embers of this series.
In what was widely interpreted as a dig at Jimmy Anderson, the Proteas skipper said: "Their bowling is experienced but some of the guys have lost some pace over the years."
He added: "The batting is not 100% best-in-the-world material, there are areas we can expose if we start well with the ball. We can find cracks. They are not unbeatable.
Miaow.

Tong Park Esholt CC: Safe option Woakes, would've liked to have seen what Footitt could do - more of a Finn replacement too.
Dan Armstrong: Good to see Woakes getting the nod again, has had an incredibly unlucky Test career so far.
South Africa: Dean Elgar, Stephen Cook, Hashim Amla, AB de Villiers (capt), JP Duminy, Temba Bavuma, Quinton de Kock (wk), Kyle Abbott, Morne Morkel, Kagiso Rabada, Dane Piedt.
England: Alastair Cook (capt), Alex Hales, Nick Compton, Joe Root, James Taylor, Ben Stokes, Jonny Bairstow (wk), Moeen Ali, Chris Woakes, Stuart Broad, James Anderson.
Umpires: Kumar Dharmasena, Chris Gaffaney
TV umpire: Rod Tucker; Match referee: Ranjan Madugalle; Reserve umpire: Shaun George
Good lord - AB de Villiers reveals South Africa have made a whopping five changes to their side. As predicted, opener Stephen Cook comes in for his debut, with bowlers Dane Piedt and Kyle Abbott returning to the XI. Keeper Quinton de Kock and batsman JP Duminy round out the changes.
For England, just the one adjustment - Chris Woakes replacing the injured Steven Finn.
England captain Alastair Cook: "We would have batted, but there is a bit of tackiness in there. We've got to do a lot of hard work in this first innings. There's a lot of personal things, this is the week a lot of guys can stamp their place in the side."
