Plate umpire Kerwin Danley was hit in the mask by a foul ball and left the field, causing the game between the Colorado Rockies and San Francisco Giants to be delayed several minutes Tuesday night. Danley was struck in the sixth inning by a foul off the bat of Colorado's Sam Hilliard. The 59-year-old Danley immediately fell backward, then slowly rolled onto his side and stayed down for several moments as Giants trainers and the other three umpires rushed in.
