The Kallis surprise and Philander's agony
What they were waiting for moment of the day
With South Africa's lead steadily growing, questions over the how they would time the declaration began. AB de Villiers had obviously been sent out to score as quickly as possible, and he and Hashim Amla added 68 runs in nine overs. The last four of those came with de Villiers reaching for a short, wide ball and sending it through the covers to reach his 15th Test century. While the Wanderers and the change-room applauded, Graeme Smith indicated it was the milestone he was waiting for and called the batsmen in. Amla was unbeaten on 74 at the time.
Tribute of the day
For the first time, the Wanderers Stadium hosted a players' day. The Long Room was filled with former cricketers from both establishment and board eras. The highlight for most of them was the opening speech given by Yusuf Garda, who played for Transvaal in 1956. Garda gave a telling oration about the history of cricket in the province across all racial divides and reminded the crowd that they were all in the same room now.
Golden arm of the day
Dale Steyn may be the go-to man for Smith, but Jacques Kallis must be his magician. The 37-year-old was brought on for a second spell after bowling just two overs before lunch and struck almost immediately. With the fourth ball of his third over, Kallis hit Azhar Ali with a length ball that struck him on the knee roll. It looked plumb but Azhar reviewed anyway and the replays confirmed it. That scalp leaves Kallis needing 12 more to get to 300 Test wickets.
Bowler of the day
For 29.1 overs in the Pakistan first innings, Robin Peterson was merely a fielder. He had not scored any runs either, so his total participation in the match was just about nothing at that point. After 34 overs of the Pakistan second innings, Peterson's only contribution was a catch at mid-on when Nasir Jamshed threw his wicket away. But then, at the start of the 35th over, Peterson was finally called on to bowl for the first time in the match. He started with two maiden overs to prove just as miserly as the rest of the attack but didn't have as good a day as some others - Peterson dropped Misbah-ul-Haq on 31 before the close.
Premature celebration of the day
Smith brought Vernon Philander back for a burst close to the end of the day and it looked a masterstroke. With his fourth ball, that held its line as it went through, Philander induced an edge from Asad Shafiq and had him caught behind on 40. Philander was mid-leap through the air and Shafiq was walking off when he was called back by the umpires as a message was relayed that the bowler had overstepped. Very little had gone Pakistan's way as far as third umpire decisions go but this time they were beneficiaries.
