Hashim Amla made a century in his 100th Test match as he and JP Duminy put South Africa in command on the first day of the third and final Test against Sri Lanka today. South Africa reached 338 for three at the close of play, with Amla unbeaten on 124 at the Wanderers Stadium. Amla became only the eighth player and second South African after former captain Graeme Smith to mark 100 Tests with a hundred. Duminy made 155 before he was caught in the penultimate over of the day, ending a third wicket partnership of 192. Amla and Duminy came together when both opening batsmen, Stephen Cook and Dean Elgar, were dismissed within six balls when the total was on 45.
