Faf du Plessis scored his fourth Test century but rain ruined the morning session as South Africa went to lunch on 289 for three on day two of the second Test against West Indies at St George’s Park on Saturday.

Resuming on his overnight score of 99, Du Plessis was made to wait another 90 minutes before play got under way, and only ended up facing two balls. The first was a gift, a leg-stump half-volley from visiting seamer Jerome Taylor that was easily dispatched to the square-leg boundary to bring up his century off 229 balls. Only six overs were bowled before the players were forced off the field again. Hashim Amla will resume after the interval on 23 along with AB de Villiers, who was on nine.

Brief Scores: South Africa 289 for 3 (Amla 23*, de Villiers 9*) v West Indies
