Oakland Athletics left-hander Jesus Luzardo is out indefinitely after breaking the pinkie on his pitching hand when he thumped a table while playing a video game on Saturday.

An X-ray showed a hairline fracture and Luzardo was put on the 10-day injured list Sunday.

Bob Melvin said he didn't know how much time Luzardo would miss or whether he would require a cast or splint on the finger.

"Before the game he was playing a video game and accidentally bumped his hand on the desk as he was playing the game," Melvin said. "He came in, was a little bit sore, training staff checked him out. We threw him in the cage before he went out there, watched him warm up. He was comfortable pitching, the training staff was comfortable with him pitching. After the game, we got an X-ray and there was a hairline in the pinkie finger."
