Pirates rookie Keller struck by liner, has bruised wrist
Keller was injured in the second inning on a comebacker hit by Miami's Garrett Cooper. Considered the Pirates' top prospect coming into the season, Keller was making his eighth major league start Tuesday night. He is 1-3 with an 8.18 ERA.
Keller was struck flush on the outer part of the wrist. The Pirates said initial imaging revealed only a bruise.
Clay Holmes relieved Keller with the game scoreless.
