Durban: Jacques Kallis hit a fluent half-century to restore South Africa's momentum after two strikes in successive overs by the West Indies slowed their progress on the second day of the third Test at Kingsmead Friday.
South Africa were 326 for three at lunch, a lead of 187, with Kallis on 52 not out.
Overnight batsmen Hashim Amla (69) and Graeme Smith (147) were out within the space of six balls after a quick-scoring start to the day.
The pair made their second wicket partnership worth 199 off 258 balls before Darren Sammy had Amla caught off a leading edge by West Indian captain Dwayne Bravo at a short mid-off position near the bowler.
Smith followed when he edged a drive against Jerome Taylor, the most impressive of the West Indian bowlers, and was caught behind by Denesh Ramdin.
Following the brace of wickets new batsmen Kallis and Ashwell Prince consolidated and the scoring rate slowed.
But Kallis was soon into his stride and reached his fifty off 63 balls when he hit the ninth four of his innings off fast bowler Fidel Edwards shortly before lunch. Prince played a quieter role and was 21 not out in a partnership of 74.
West Indian hopes that the bowlers would get assistance from conditions early in the day failed to materialize. Bowlers prospered when the West Indies were bowled out for 139 in overcast conditions on the first day but the sun was shining brightly from the start of play Friday.
Brief Scores (at lunch, D-2):
West Indies Ist innings 139 all out Vs South Africa 326/3 (Smith 147, Hashim Amla 69, Kallis 52; Taylor 1 for 51, Sammy 1 for 70, Powell 1 for 78).
