Port Elizabeth: The West Indies had cause to rue four missed chances as South Africa moved steadily towards a substantial first innings total on the first day of the second Test at St George's Park on Friday.
South Africa were 270 for two at stump after being sent in to bat in overcast conditions.
Dean Elgar (121) and Faf du Plessis (99 not out) put on an 179 for the second wicket but both should have been dismissed.
Du Plessis was put down by Marlon Samuels at gully off Jerome Taylor when he had made eight and again by Devon Smith diving to his right off left-arm spinner Suleiman Benn when he was on 26.
One ball after Du Plessis' second escape, the left-handed Elgar went down the wicket to Benn and was well out of his ground as the ball squeezed through to hit low on the pad of captain and wicketkeeper Denesh Ramdin.
Elgar was on 48 and to add insult to injury for the disappointed bowler he went down the wicket again just after that and lofted Benn to the straight boundary to raise his fifty. He also could have been run out on 73. After a mix-up with Du Plessis, he was several metres short of safety when Kenroy Peters' throw from midwicket missed the stumps at the bowler's end.
West Indies first wicket came after Elgar and Alviro Petersen had put on 47 for the first wicket. Petersen played a rash stroke against Shannon Gabriel and was caught by Leon Johnson, running back from cover.
Debutant Peters picked up wicket of Deal Elger, Dinesh Ramdin takes catch behind the wicekt.
Earlier, West Indies have won the toss and have opted to field.
Temba Bavuma will make his Test debut for South Africa, he replaces the injured Quinton de Kock. Bavuma becomes the first black batsman to play for South Africa, the sixth overall.
Another change for South Africa is Imran Tahir in for Kyle Abbott.
Three changes for West Indies -- Jermaine Blackwood, Sheldon Cottrell and the injured Kemar Roach left out and Shannon Gabriel, West Indies ODI captain Jason Holder and there is also a debut for the 32-year old Kenroy Peters are in. The left-arm fast bowler has a first-class average of 20.
