Pomeranz exits start with shoulder tightness

HOUSTON -- A's starter Drew Pomeranz exited his Monday start in Houston with one out in the fifth inning with left shoulder tightness.

After the game, a 2-1 A's victory, Pomeranz said it was the AC joint in his shoulder that flared up during the outing, "and it didn't go away." He couldn't say for sure whether he'd be able to make his next start, but noted his past experiences with the same issue have never been serious.

"It just kind of kept bothering me," said Pomeranz. "I know what it is, there's some soreness up there, we'll see how it is tomorrow and go from there."

Pomeranz totaled 82 pitches before his departure, leaving two men on base with one out for reliever Edward Mujica, who left the frame unscathed.

The left-handed Pomeranz, making his eighth start of the season, allowed one run on two hits and walked five, with two strikeouts.
