Finn bends his back trying to make immediate amends for his spill but Morris and Bavuma are equal to it. The caught-and-bowled chance beat Finn for pace but England could really have done with breaking this partnership.

England are getting very familiar with dropped catches in this Test. It's another tough chance in fairness but Finn fails to wrap his mitts around a Morris drive straight back at the bowler.

"Bavuma looks a decent little player but if you bowl a few dots he doesn't like it."

This pair have scored freely to bring the deficit down quickly and Bavuma continues the trend with a square sweep off Ali to the fence after manoeuvring the field.

"If they can get to tea, the deficit is going to be 75 or less than that."

Dan Gee: Awesome from Bavuma but this is buffet bowling by Finn.

Stokes' sledging is clearly not paying dividends and he's also been removed from the attack with Moeen Ali resuming over the wicket. Bit of turn off the surface too, but not enough to trouble Bavuma. Just one off the over.

"Those wickets have spurred South Africa into action. They have to get that deficit down."

Silky stuff from Bavuma, effortlessly pushing Finn through the covers. And there's plenty more as he plays late to guide the ball behind point before pulling through mid-wicket for a third consecutive boundary. Only a diving stop from Compton prevents a fourth.

South Africa bring up the 500 and these two have raced to their 50 partnership.

Despite those three quick wickets, Bavuma has settled very quickly, easily dealing with Stokes' pace and line. And the ginger tyro is livid, making his thoughts known to the diminutive South African, which draws a warning from the umpires. 'Pick on someone your own size', perhaps.

"The game has moved forward and has been quite interesting since lunch but I still feel South Africa have done enough. England can still make it awkward for them but South Africa have taken up a lot of time and England still haven't got them out."

Finn continues to probe outside off but Bavuma is picking up length expertly and rolls a shorter delivery through the vacant mid-wicket area for four. That's an unwanted century of runs conceded for Finn too. A single and a dot to finish.

Not there Ben - a tame short ball is well struck up and over to the fence by Bavuma, who's canny enough to dab one and get off strike next up. Morris is no mug with the bat either, punching Stokes off the back foot for another couple.

"I fancy Finn to get Morris out around off stump."

And Finn is fizzing straight away as he narrowly misses Morris' off peg with a ball that just shapes away. Morris then has his revenge, guiding an over-pitched delivery through third man for four before Finn hits back as the South African edges just short of the slips. England on the up.

Thanks Justin. Drinks this time yesterday gave England renewed spirit. Any more this time round and we could be in for a thrilling finish to the day. Here's hoping...

I'm off for a cool beverage of my own. Jack Skelton will see you through the next hour until tea.
