That looked like a lot when New Zealand's top order failed once again and they finished the day still up against it three runs behind on 65-4 with Williamson on 41 and Daniel Vettori yet to score. It looked like it might have been healthier but they lost Taylor for 17 just 2.2 overs before the close of play.
New Zealand's second-innings collapse didn't quite match the events of yesterday but that was extraordinary and seven for three is bad enough at any time.
It was car crash material as Rob Nicol, who looks out of his depth in test cricket, Martin Guptill (1) and Brendon McCullum (5) surrendered their wickets meekly and handed back any initiative they had worked so hard to grasp.
Nicol's run in this series reads 6, 19, 2 and 1 and his days in the side could be numbered. South Africa will hope he remains because they have his.
Today he was bowled when the ball rolled down from his thigh onto the inside of the pad and hand and onto the stumps. It was a cruel way to go but it's called test cricket for a reason.
Dean Brownlie is expected to be fit in time to play next week in Wellington, and there is a school of thought he needs to play domestic cricket before being thrust back in, but he is a fighter and his average of 47.85 from four tests looks significantly healthier than Nicol's.
It would mean McCullum moving back up the order to open and Kane Williamson into three but McCullum is basically opening now anyway.
Vernon Philander continued his incredible start in test cricket, picking up another two today to take his tally to 41 wickets in his sixth test at 14.36 _ and is on target to be the first bowler to 50 wickets since the Nineteenth Century.
Williamson and Taylor restored some order with a partnership of 57 but Williamson and Vettori will need to bat for considerable time today if New Zealand are to post a competitive target.
The pitch is sluggish and dying but certainly not as lethal as 24 wickets in two days would suggest and de Villiers (83) proved batsmen can prosper if they are prepared to work hard to get in and play good cricket shots.
