PHOENIX -- Home-plate umpire Jim Wolf was forced to leave the game after he was struck in the facemask by a foul tip in the bottom of second inning of Friday night's Dodgers-D-backs game at Chase Field.
D-backs shortstop Nick Ahmed tipped a Pedro Baez pitch and it hit Wolf flush on the mask. Wolf's legs buckled and he fell to his knees.
After being looked at by D-backs head athletic trainer Ken Crenshaw, Wolf stayed in the game and finished the inning.
After the inning was completed however, Wolf left the game and was replaced behind the plate by first-base umpire Alan Porter.
