South Africa crushed Zimbabwe by an innings and 120 runs inside two days in their one-off day-night Test at St George's Park on Wednesday.

Forced to follow on after being bowled out for 68 in their first innings, Zimbabwe were shot out for 121 runs in their second innings. The match ended before the scheduled dinner break on the second day.

Fast bowler Morne Morkel was the destroyer in the first innings, taking five for 21, but medium-pacer Andile Phehlukwayo and left-arm spinner Keshav Maharaj engineered the second-innings collapse.

Phehlukwayo took three for 13 and Maharaj claimed five for 59.

South Africa were without wicketkeeper Quinton de Kock, who suffered a low grade hamstring strain while batting on Monday.
