Younis reached his 21st Test century -- and his fourth

against South Africa -- after facing 192 balls and hitting six fours and three sixes, all of the sixes coming off left-arm spinner Robin Peterson. The stocky Shafiq followed in the last over with the old ball, notching his third Test hundred off 201 balls with 13 fours and a six. Steyn appeared to have made a breakthrough with his third delivery with the new ball when Younis, on 105, was adjudged leg before wicket by umpire Steve Davis. But the batsman immediately called for a review which showed that the ball flicked the inside edge of his bat before crashing into his front pad. Younis then fell victim to a successful review by South Africa after being given not out by umpire Bruce Oxenford. Replays showed he had been caught behind off an inside edge and his thigh pad. The stand lasted for 439 balls and gave Pakistan heart after a poor start. Opening batsmen Mohammad Hafeez and Nasir Jamshed started cautiously, scoring just ten runs before the left-handed Jamshed was caught behind off Philander for three. He had survived a chance to Faf du Plessis at gully off the previous delivery. Hafeez edged Steyn to first slip after making 17 before the tall Morkel took two wickets in an over, having Azhar Ali caught behind attempting an extravagant drive before Pakistan captain Misbah-ul-Haq was caught at short leg off a sharply rising delivery.
