BOSTON (AP) Mike Carp's pinch-hit single in the 10th inning gave the Boston Red Sox a 4-3 win Thursday for their second straight walk-off victory over the Chicago White Sox.

Pinch-hitter Daniel Nava drew a leadoff walk and went to second on a sacrifice by Mookie Betts. Stephen Drew, in an 0-for-15 slump, was intentionally walked by Ronald Belisario (3-6). Carp then batted for David Ross and lined a single between shortstop and third base as Nava scored the winning run for the second consecutive game.

In Boston's 5-4 comeback victory Wednesday night, Nava doubled in Betts for the tying run in the ninth and scored on Brock Holt's game-winning single.
