Mayers took three wickets, while Roach got two though South Africa ended the session with a lead of over 200
Tea South Africa 63 for 6 (van der Dussen 22*, Mayers 3-14, Roach 2-26) and 298 lead West Indies 149 (Blackwood 49, Mulder 3-1) by 203 runs
Play started two hours and forty minutes after the scheduled time thanks to a wet outfield following heavy morning showers, and the first session finished 30 minutes early as the rain returned. The moisture was not having much effect on the conditions, but the West Indies pack generated movement off the seam and challenged South Africa with tight lines and challenging lengths.
Roach struck with his third delivery when Aiden Markram was forced to play at a ball that moved away from him and outside edged to Holder at second slip. Keegan Petersen was almost dismissed off the next ball as well when Roach beat his inside-edge, but the ball snuck through the bat-pad gap. In Roach’s next over, Petersen inside-edged onto his pads; in the one that followed, Roach beat him with a full delivery, and two overs after that, Roach got his second wicket though it wasn’t Petersen. Dean Elgar’s uncertain innings ended when he pushed at a ball outside off that seamed away from him and edged to second slip.
Petersen saw off Roach and was just starting to settle, though he would be disappointed with his lack of foot movement against Mayers, as he bottom-edged onto his stumps. He looked to cut a short and wide delivery but stayed rooted in his crease instead of moving outside off, and chopped it on, thus finishing his debut series with a top-score of 19.
Mayers continued to ask questions of South Africa and could have had Kyle Verreynne caught in the cordon as well when he edged a full delivery between third slip and gully. And though Verreynne took South Africa’s lead past 200, he was caught behind off the next ball off Mayers.
West Indies snared the biggest fish four balls later when Quinton de Kock defended a Holder delivery away from his body and edged to Joshua Da Silva. After a hundred in the first Test and 96 in the first innings of this game, de Kock was dismissed for a duck, and West Indies could see into the lower order.
Wiaan Mulder, who is in the side as a batting allrounder, has so far done more with the ball and continued in that vein. He drove at a Mayers’ delivery that was pitched on fourth stump, but edged and was caught at gully. Rassie van der Dussen then took South Africa to tea, with just the tail to come.
