DENVER -- Baltimore Orioles pitcher Dean Kremer left Saturday night's game at Colorado after he was hit by a line drive in the fourth inning.

Kremer was struck on his right forearm, just below his wrist, when Jordan Beck hit a liner back up the middle on a four-seam fastball. The ball went to shortstop Gunnar Henderson, who threw to second for a forceout.

Kremer was examined by team athletic trainers before he was replaced by Keegan Akin. The 28-year-old right-hander was diagnosed with a right forearm contusion. X-rays were negative.

Kremer was charged with four runs and six hits in 3 1/3 innings in his shortest start of the season.
