Shivnarine Chanderpaul equalled the world record for most consecutive Test half-centuries as the West Indies made solid progress on the second day of the first Test against South Africa at St George's Park.
The West Indies were 357 for six at lunch, with Chanderpaul unbeaten on 70.
Fast bowler Makhaya Ntini, armed with the second new ball, made two early strikes for South Africa before Chanderpaul and Darren Sammy came together in an unbeaten seventh wicket stand of 53. The tall Sammy played some punishing shots as he made 35 not out.
Ntini caught Dwayne Bravo for 12 off his own bowling when the all-rounder tried to work him to leg but the ball went high off a leading edge towards point. Ntini and gully fielder Herschelle Gibbs converged and almost collided before Ntini clutched the ball.
Ntini followed up by having Denesh Ramdin caught behind for one.
It was Chanderpaul's seventh consecutive score of 50 or better, equalling a mark set by fellow West Indian Everton Weekes in 1948 and 1949 and repeated by Andy Flower of Zimbabwe in 2000 and 2001.
Chanderpaul's sequence started when he made 69 against Pakistan in Karachi in November 2006 and continued when he had scores of 74, 50, 116 not out, 136 not out and 70 in a series in England earlier this year.
The West Indies resumed Thursday on 281 for four, with the left-handed Chanderpaul on 43. He reached his half-century when he pulled Dale Steyn to the boundary 40 minutes into the second day's play. He had faced 147 balls.
Chanderpaul continued to bat patiently while Sammy was the aggressor in their partnership.
