Oakland Athletics pitcher Brandon McCarthy left Wednesday's game against the Los Angeles Angels of Anaheim after being hit in the head by a line drive.
In the top of the fourth, Erick Aybar hit a line drive back at McCarthy. The ball nailed McCarthy on the side of the head, sending the Oakland starter to the ground.
McCarthy was able to walk off the field after being attended to for several minutes. He gave up three runs on five hits before exiting the contest.
"Brandon McCarthy is conscious and doing well," Oakland said in a statement after the game. "Doctors at Summit Hospital want him to stay overnight for further observation. He will not accompany the team on the charter flight to Seattle tomorrow afternoon."
