BOSTON (AP) Red Sox outfielder Rusney Castillo left Friday's game against Seattle after fouling a ball off his left foot.

Castillo, who hit a two-run homer earlier in the game, fouled a ball off his foot in the fourth inning. He finished the at-bat, taking a called third strike, before he was replaced in the lineup by Alejandro De Aza in the top of the fifth.

Boston leads 9-1.
