South Africa reached 227-3 at stumps on day two of the third Test against the West Indies, leaving them just 102 runs short of the tourists' first-innings total.
Having reached his half-century just before tea, Faf du Plessis continued to add the runs in the evening session until Denesh Ramdin stumped him off a Sulieman Benn delivery.
Hashim Amla built on the solid start that he had made in the afternoon, going past the 50-run mark shortly before the close of play.
AB de Villiers joined Amla at the crease following Du Plessis's dismissal, and he made a quick start, reaching 32 off just 52 balls before the end of the day.
