Conor Gillaspie hit a run-scoring single in the ninth inning to score Dewayne Wise, lifting the Chicago White Sox to a 2-1 win over the Miami Marlins on Saturday night.
Derek Dietrich homered in the top of the ninth to spoil Jake Peavy's shutout bid, but in the bottom half, Gillaspie drove in Wise - who had come in as a defensive replacement - to give the White Sox their eighth win in 11 games.
Peavy (6-2) struck out five and allowed six hits in the complete-game effort, his longest outing of the season.
Ryan Webb (1-3) gave up Gillaspie's single to take the loss for Miami, which dropped its fourth straight and 11th in the last 13 games.
Alexei Ramirez gave Chicago a 1-0 lead with an RBI double in the third.
