Amla 157*, Du Plessis 51*
Amla dropped on 76 & 120
De Villiers 88 - only wicket to fall in day
SA need 430 to avoid follow-on
England lead 1-0 in four-match series
Suddenly England look a team inspired and Finn is leading the charge. New man Faf du Plessis gets a great cherry first up and edges streakily through the slip cordon for four. Anderson's catch looks better at second glance, it was at the limit of his reach and needed a juggle to stick in his palm.

De Villiers c Anderson b Finn 88 (SA 268-3)
Image source, AFP/GETTYDon't you love it when a plan comes together? Finn drops short once again to De Villiers, who pulls straight to Anderson at mid-wicket. The Burnley Express makes amends for dropping Amla earlier to hold on at the second attempt and remove De Villiers 12 short of his century.

"This is the most threatening England have looked all day."
After a brief flurry of action, the South African pair are looking to quell England's excitement but Stokes has other ideas. A short delivery draws a leading edge from Amla that falls well clear of any fielders before the centurion unconvincingly guides another down to first slip. Plenty of short stuff all round now.

Ned in Somerset: I think all nations should play with Duke balls as it would even up the competition between bat and ball and create a more entertaining game on flat wickets such as this one. Just saying!
Image source, Getty ImagesA change of approach from England as Finn is clearly targeting De Villiers with the short ball. The Proteas star leans away, rides the bounce and steers down to fine leg for one from three consecutive balls back of a length. A short leg is in for Amla but he also deals with Finn's threat for now.

"I don't see a collapse coming. These are half chances, it is still a fantastic batting pitch."
For all the dropped catches, England's ground fielding has been good this session - James Taylor making a fine diving stop to prevent an Amla drive reaching the fence. Stokes is back on the money for the rest of the over that yields two runs.
Image source, AFP/GETTYFinn really does get things happening. The paceman airs his frustrations at Compton's dropped catch with a well-directed bouncer that De Villiers flashes wildly at to finish the over.

"If I was Cook I'd say to Amla, 'when you've had enough batting could you just let it hit the stumps because I am not sure we can catch you'. They weren't simple but they are catchable in Test cricket."

"It's very difficult to know what a captain can do. If you have a Waqar Younis with reverse swing maybe but there are not many of them."
Image source, Getty ImagesStokes flashed a rueful grin straight after England's appeal and sure enough the third umpire Rod Tucker confirms a big inside edge to reprieve De Villiers.
Two reviews in two overs though, England starting to excite.
Image source, Getty ImagesStokes gets one to slant back into De Villiers' pads and umpire Aleem Dar raises the finger! But De Villiers, on 85, raises his bat to signal a review almost immediately...
Image source, Getty ImagesFinn was England's most threatening bowler this morning and again the Middlesex man makes things happen. Amla survived what would've been a cruel end to a brilliant innings. But Finn also had De Villiers in trouble in the over, edging through the vacant third-slip area for four.
SA 258-2
Relief for South Africa as Amla was quick on the turn to make his ground before the bails were disturbed. The deadlock remains unbroken...
De Villiers hits the fourth ball of Steven Finn's new spell straight down the ground and the lanky bowler gets a finger on it to divert the ball on to the stumps.
Is Hashim Amla out of his ground at the non-striker's end? We're going upstairs...

Will in Hale: Longing to see the blue background of a wicket falling. Tempted to try some reverse mockers. The Amla's not going anywhere!
SA 254-2 (trail by 375)
Image source, AFP/GETTYAnderson, into his 18th over, has struggled to find the seam movement he extracted in the first over with the new ball. But I'd argue that he's been a smidge too short this afternoon. Amla forces one through point off the back foot. I'm taking a breather from the text commentary. Hopefully debutant Jack Skelton can break this partnership...
