West Indies captain Kraigg Brathwaite won the toss and chose to bat first against South Africa on the opening day of the first match of a two-Test series in St Lucia on Thursday. West Indies gave a debut to 19-year-old fast bowler Jayden Seales, who has played just one first-class match previously. In contrast, South Africa's two debutants, middle-order batsmen Keegan Peterson and Kyle Verrynne, who gets his chance because of a hip injury to the experienced Temba Bavuma, have both played more than 40 first-class matches. This is the first meeting in Test cricket between the two teams in the West Indies since 2010 and the first time since their historic one-off meeting in 1992 in Barbados that the Caribbean side are ranked higher than the Proteas ahead of a series.
