Big appeal from TRJ as the ball hits Bavuma's pad, and England invoke the DRS for the first time today...

Stephan Shemilt
BBC Sport at The Oval

A ground on the last day if a Test can often have the feeling of a ghost town, more people who have to be there than those who have chosen to attend. Not at The Oval, where the crowd is expected to be 10,000.

Moeen begins the 50th over of the innings, Elgar drills a single to wide mid-off to move to 97 from 147 balls. Bavuma is also sitting pretty, moving to 32 from 96.

I think the umpire might have had to give Elgar out with that little squiggle because it happened at the precise moment the ball passed the bat.

Alec Stewart adds: I don't think Elgar hit that one, there was only just a little murmur and when you hit it you see spikes. DRS is there to remove the shocker - and this wasn't a shocker, given that we're still debating whether he even hit it.

Elgar's never going to trouble the selectors of the Aesthetically Pleasing XI (hey, not everyone can be David Gower or Kumar Sangakkara), but that's a glorious shot - a straight drive for four that's little more than a forward prod, which takes him to 95. There's an even bigger round of applause next ball when Stokes pulls off one of his Superman dives at gully to cut off another likely boundary. Good cricket all round. Elgar moves to 96 with a single.

I'm sure the South Africans would have thought about it half-an-hour at a time and trying to get to 12 with still only four wickets down.

It's the 100 partnership, this pair's second in Test cricket and it has taken them 184 balls.

Bavuma steers off-spinner Moeen Ali for a single to bring up the century stand while Elgar, still adjusting his bat rubber between deliveries, rotates the strike with a leg bye.

I'm pleased Joe Root has made this bowling change, can Moeen hit that pancake about 8-10 pigeon paces a little wide of off stump which will have the batsmen guessing?

It's a moral victory of sorts for South Africa when both of England's opening bowlers of day five have been taken off. With Moeen Ali standing by to replace Broad at the Vauxhall End, there's a brief hold-up as Dean Elgar needs a new grip on his bat - and we all know how fiddly those bat-rubber-applicator things are.

While we're waiting, take a look at another Elgar boundary.

With the Ashes coming up you wonder if Roland-Jones would suit Australian pitches and I'd say he would, he doesn't just rely on swing. He has just bowled a little bit fuller than Broad or Anderson and it's no coincidence he has been rewarded with wickets. You can see he has worked with Richard Johnson and Angus Fraser who were also very accurate.

Having taken those five wickets in the first innings - and snared the dangerous Hashim Amla in both innings - debutant Toby Roland-Jones replaces Stokes at the Pavilion End. Bavuma resumes his defiance, knocking a single to fine leg.

Bavuma plays the ball very late under his eyeline, if he gets beaten it doesn't look as though it fazes him at all, he's mentally strong. He has learned quickly which is good to see because some of the South African batsmen have a lot to learn.

As a newspaper journalist of many years' standing as well as a peerless broadcaster, Richie would mourn the demise of the sub-editor!

With Toby Roland-Jones going through his warm-up exercises on the boundary, Broad begins a new over and Bavuma punches a well-run three through the covers. Elgar moves into the nineties with a couple off his legs. And though the total runs are largely irrelevant today, that's 150 up for the Proteas.

I'd have been tempted to start with the off-spinner against Elgar because he's so used to facing the seamers, it might have just surprised him. Stokes has not quite found the rhythm we saw last night where he was nearly 90mph and Elgar has played some lovely shots.

Captain Joe Root has a brief chat with vice-captain Stokes before the new over - Root goes from second slip to leg gully, a short leg is brought in and Keaton Jennings is dispatched to the square leg boundary. More bumpers on the way, or a bluff? Though with so many runs to play with, Michael Vaughan on TMS still thinks they could keep a second slip in... But having set his field up for a bouncer, when Stokes bowls wide outside off stump, Elgar forces him for four backward of point. (And it was a no-ball).

South Africa have made it through the first half-hour unscathed.

We hope you're enjoying the in-play highlights this summer. Here's our first of the day - a four from Elgar.

I think Bavuma is a really nice player form the old school. He could be at number four and leave De Kock to number six. I saw Bavuma this morning and asked him what he made of it and he said it's absolutely fine until the lights come on.

Broad, who may still be unaware of how he'd have a wicket to his name this morning if they'd reviewed that caught-behind against Elgar, finds Bavuma on the defensive - while a TV graphic shows how good he's been at leaving the ball outside off stump this morning.

Maiden over. At least with more than 350 runs still in the bank, England won't need to remove their attacking fielders.
