Centurion - AB de Villiers scoring a century and Vernon Philander reaching his highest Test score were just two of the milestones reached for South Africa in the first session of play in Centurion on Saturday.Resuming on 334/6, in the third and final Test, South Africa were all out for 409, 20 minutes before lunch.On 98 overnight, De Villiers took seven balls to reach his 16th Test century, and third against Pakistan. He was eventually caught in the deep by Asad Shafiq for 121, after facing 215 deliveries and smashing 15 boundaries.Philander brought up his second Test half-century off the next ball, taking 86 balls, and it was not long before the pair celebrated a century partnership for the seventh wicket.After surviving one chance, Philander eventually edged Younus Khan to Hafeez at first slip and a review proved the fielder had indeed taken a legitimate catch and Philander was given out for 74.It was his highest Test score after the 61 he made against England at Lords.Their valuable seventh wicket stand was worth 129 runs in the end, and included 13 fours.Right-arm seamer Kyle Abbott scored his first runs in Test cricket.The 25-year-old Dolphins’ bowler was rewarded for an excellent season in domestic cricket. He was roped into the team after Jacques Kallis strained his calf muscle in the nets and the selectors decided to go for a fourth seamer instead of opting for another batsman.Pakistan’s fielding and bowling were both particularly shoddy as they spilt a couple of catches. Philander was dropped on 45, off Rahat Ali after there was a mix up behind the stumps between the wicketkeeper and first slip.Then Rahat was the culprit when he dropped a sitter at fine-leg when De Villiers was on 107.Rahat’s bowling deteriorated and his figures included six no-balls and six wides. In was almost an injustice as he grabbed six wickets for 127 runs.Ehsan Adil took 2-54 on debut was did not bowl again after he limped off injured on Friday.Pakistan faced five overs before lunch and reached 9/0 at the interval, still trailling the Proteas by 400 runs.South Africa have already clinched the series, 2-0.
