(ESPNCRICINFO) – A Test that seemed destined for a draw is set for a thrilling final day, weather-permitting, after South Africa grabbed the game by the scruff of the neck on the fourth evening. Despite having only two hours of play on Saturday, South Africa took a 124-run first-innings lead after they bowled West Indies out for 233 and then scored 30 runs in five overs to put themselves in a position to push for a win.

Rain has affected every day of this Test so far. It seemed as if play wouldn’t get underway today as more than 50mm of rain in some areas of the island had raised a yellow-level alert. But, after a six hour delay, play did start at Queen’s Park Oval and South Africa took control. They forced a West Indian collapse of 6 for 60 in 16.1 overs to ensure they were batting again by the end of the day.

Given the amount of time lost overall, and particularly on the first and fourth days, that this much has happened is impressive enough. Only 15 overs were possible on day one and 30 were scheduled for day four and though the action was truncated, it was absorbing.

Matters resumed with South Africa 13 overs away from the second new ball, and they restarted with spin from both ends, which meant Aiden Markram had to begin the day’s proceedings. Jason Holder immediately took the opportunity to put pressure on South Africa’s white-ball captain by creaming the first ball through the covers for four. He went on to hit Markram over mid-off and toward deep midwicket, but Markram won the mini-battle when he flattened Holder’s off stump in his tenth over. Three balls later, Keshav Maharaj had Joshua da Silva caught at mid-on to claim his fourth wicket of the innings.

Maharaj would have had five in his next over when Kemar Roach, on 0, popped a chance up in the direction of David Bedingham at silly point. It needed quick reactions and a bit of luck to stick, but the ball just evaded Bedingham’s outstretched right hand.

The new ball was taken as soon as it became available but South Africa stuck with the spinners. Markram went on to bowl an eight-over spell before being replaced by Kagiso Rabada, who took his 292nd Test wicket with this fourth ball. Bedingham made no mistake at first-slip and took the catch to dismiss Kavem Hodge. Rabada’s discipline continued to dismantle West Indies’ lower order. Gudakesh Motie met a full delivery by closing the face of the bat too early and edged to Markram at second slip, and Roach was struck just under the knee-roll on the front pad to be given out lbw. He reviewed only to see three reds from ball-tracking on the replay.
