9.5 rips off the glove and that's the breakthrough! Snorter and snortje! The short-of-length attack finally pays off, and it's Sri Lanka's captain who is extracted. Wasn't hitting the stumps, of course, but Nortje got his line right and Karunaratne couldn't withdraw his hands in time, de Kock gleefully accepting a looping offering 19/1

20.1 gone this time! Perera's fun comes to an end. That's how to bowl to Perera. Mulder's pace, or lack thereof, means he can't just throw the bat and get away with it. Length ball, not enough room outside off to free his arms, and instead a thick edge on a half-formed drive finds Markram in the cordon 71/2

22.5 edged, gone, and Mulder has three in no time! An innings to sum up Thirimanne's Test career. Slightly full of a length, angled across him as he looked to clip into the leg side, but a hint of nip away off the seam means it takes the edge. Faf takes a sharp low catch at second slip, and Thirimanne throws away a start, just before the interval, and just as he was starting to look set 80/4

20.5 edged again, and gone this time! Mulder has two in the over! Perfect length again, with a hint of nibble away from the bat off the seam. Mendis' hands were harder this time, and it kissed the shoulder of the bat, looping up for a straightforward catch at first slip by RvdD. Almost squared him up 71/3

23.6 and it brings a wicket! Back of a length and some extra bounce, and Bhanuka decides to play at it. It gets big on him, takes the outside edge near the splice of the bat, and flies to first slip where RvdD takes an excellent catch. A nothing shot, if truth be told, and Bhanuka will be furious at himself to get out to the last ball of the session 84/5

25.5 another difficult take but de Kock swallows it! Thick edge as Dickwella drove away from his body, and Quinny went soaring full length to his left to take the catch! May well have carried to first slip, but the captain takes responsibility, and SL slip further into trouble 93/6

29.5 gottim! Big booming drive without foot movement and he nicks behind... or does he? Shanaka reviews, though it seems more out of hope than expectation as UltraEdge quickly reveals a feather. Nortje has his fourth, and the smell of blood in his nostrils 110/7

37.1 feathered behind, and Hasaranga falls straight after drinks! Length ball on fifth or sixth stump, and Hasaranga poked at it dozily, away from his body. He reviews, but UltraEdge confirms a spike, and de Kock took a straightforward catch behind the stumps. Sipamla gets his first, and Sri Lanka are deep in the mud 149/8

38.3 gone this time! Nortje has five and lets out a broad grin! 89mph/143kph, short ball aimed at the badge of the helmet, and Chameera swats carelessly at it. He gets a decent edge on it, giving de Kock his fifth catch of the innings - four of them off Nortje. Sri Lanka nine down. 151/9

40.3 tiiiiiimber! Six-for for Nortje. Asitha has realised that there's only so much point trying to survive when facing 90mph/145kph rockets, and swings the bat wildly once more, jumping towards the leg side. But Nortje fires in a yorker, and Asitha looks round to see middle stump out the ground, and leg stump angled towards square leg. Nortje leads the team off, with career-best figures of 6 for 56 to his name. 157/10

51.2 edged, and straight into the hands of first slip! The drinks break strikes, and Elgar is gutted as he plods off ... his first false stroke of the morning, just in the channel outside off, wider on the stumps, and a hard-handed prod induced a lob off the edge, just pushing in front of his body for once. An opening! 218/2

7.3 steered to slip and Asitha claims the breakthrough on debut! Extra bounce as the ball leaves him and Markram can only thick-edge a low catch to second! That'll perk up SL after a torrid day so far 34/1

52.3 huge appeal for a strangle down the leg side! Umpire Erasmus is unmoved, but Sri Lanka are up in unison! The decision has been reviewed - a big wipe into a pull to the leg-side delivery, if there was a noise, it can't have been anything but bat... or glove! Rassie is already walking! 218/3

56.6 exceptional bowling! After unnerving Faf with the lifter one ball earlier, Shanaka probed that uncertainty on a fuller length with a hint of nibble off the pitch, and a skimming edge was scooped up by Dickwella! South Africa have lost their stranglehold since drinks! 235/4

57.6 edged again, gone again! What is going on out there! South Africa have lost their grip in the last half an hour, as this time it's de Kock who is lured outside off on the full length. A hint of swing is his downfall, as he goes once again with hard hands, and scuffs a fat edge low to second slip! 241/5

67.6 shoulders arms and that's salmon and trout! Bavuma is going to review this, but Vishwa has done him like a kipper here... Slippery in-ducker and Hawk-Eye has it smashing into middle and off! Temba blunders again, padding up to a straight one, and even the technology can't save him from this misjudgement. SL's quicks rampant 276/8

63.2 struck on the full - given! Looked a touch leg side to me, though, and Mulder reviews Adrian Holdstock's decision. What does Hawk-Eye say? Umpire's call on impact, Mulder's a goner! That was so tight, I'm not sure of the exact margins employed, but definitely appeared to be outside the line of leg stump to the naked eye. But the decision stands, and Mulder walks off disappointed 257/6

64.6 gets him this time, Asitha rips out another! Beautiful line, curved like a scimitar and whipping wickedly through to Dickwella via the outside edge! Second wicket of an impressive debut for Asitha, who's brought some spunk to this attack. SA rocking a little on their heels here 262/7

69.3 bagged at slip, Vishwa has four! Attacking line, and the ball straightens enough from round the wicket to clatter the outside edge and fly to second, where Mendis stays low to grab it at shoulder height! SL are lovin' it, lovin' it, lovin' it 283/9

75.4 back of a length again, outside off, stabbed to gully, and VIshwa Fernando has his five-for! Hugely deserved, and smiles all round for Sri Lanka. They have clawed their way back from oblivion with a big two-hour stint 302/10

43.5 skied up to square leg, and Mulder takes the catch! Oh Dimuth, what have you done? He's late on the shot, looking to pull a back-of-a-length ball, aimed into the body. The top edge loops up into the leg side, and Mulder hardly has to move to get underneath it. Nortje's extra pace makes the breakthrough, and Karunaratne has to go after a hard-earned ton 176/5

2.2 that's the money shot from Ngidi! Perfect line from round the wicket, impeccable seam position, zipping back off the deck, through the slenderest of gates as Perera throws his hands into a cramped drive, and plinking off the top of the leg bail! South Africa are up and running, and well, just as well there are no tickets to refund for day three onwards! 1/1

22.6 gone, tickled down the leg side! A tame way to go, and that sums up Thirimanne's career, really... Nothing ball on the hip, maybe a bit of extra bounce, but he only succeeds in getting a touch of glove through to de Kock. Disappointment writ large for the tourists. SA are back in it 86/2

24.1 would you believe it, another strangle down leg! Flying catch by de Kock and Mendis goes first ball for a pair! Went straight off the face of the bat, on another day it flies for four - but this time the keeper was there, two-handed to his left, similar to his take in the first innings to get Dickwella. Mendis curses his luck as he slopes off. Meanwhile, Ngidi is on a hat-trick! 92/3

27.3 goes for the pull ... and what a sensational take from Maharaj! It's a sharp delivery from Nortje, rising from just back of a length at 150kph, and slamming the top edge as Bhanuka is too late on the stroke. But there's a lot of work to do, running back at midwicket, where Maharaj flings himself full-length, clings on his fingertips, and from a promising platform, Sri Lanka are unravelling at pace! 109/4

44.3 oh Dickwella. Oh Dickwella. What have you done? Why do you do these things? He has looked in good touch this morning but this is a truly dreadful shot. Slightly full of a length from Ngidi, nipping away off the seam, and he has a half-hearted, ill-conceived swipe at it, with his weight all over the place. He was looking to go down the ground or over mid-on, but it skews up off the edge, and Bavuma gets round to take the catch at mid-off. Ngidi has his fourth, and South Africa are threatening to do this in a hurry. 181/6

50.5 chipped up, and gone! Another tame, tame dismissal. Good length on off stump, no great menace in the delivery, and Shanaka plays a shot that is neither one thing nor the other. He looks to attack it, but almost realises during the stroke that he's making a grave error. That means it ends up being a half-hearted lunge, and it loops up into the grateful hands of Sipamla at mid-on. 190/7

54.5 that's revolting! A fraction fuller, and a hideous hack off a full length. Sipamla knocks back the off and middle stumps, and Sri Lanka's series is nearly cooked. For the fourth time this morning, a disciplined innings ends with a donation of a wicket. Those hopes of a three-figure target are distant now 209/8

56.4 huge appeal! For the second time in as many overs, there's an apparent catch behind the wicket, but this time it's South Africa reviewing. Climbing off the seam once again, and yep, this time there's a clear spike as the ball passes bat. Sri Lanka are nine down 210/9

56.5 perfection to finish the innings! Off stump line, nip off the seam, pace and aggression, pings past the outside edge of a not-very-well aligned batsman, and plucks out the off stump to wrap up an innings that promised much more first-thing this morning 211/10
