Batista suffers groin strain

Righty leaves opener against A's in second inning

SEATTLE -- Veteran right-hander Miguel Batista, coming off a superb outing against the Angels, was forced to leave Friday night's start against the Athletics in the second inning with a mild groin strain on his right side.

Batista departed after issuing a four-pitch leadoff walk to Kurt Suzuki, the fifth free pass issued in one-plus innings.

Four walks, including three in a row with one out in the first inning, contributed to a three-run outburst by the Athletics. Batista needed 43 pitches to make it through the inning and 22 of them were called balls.

It was a complete turnaround from the game he pitched against the Angels last Sunday afternoon in Anaheim. Batista, the Mariners' top winner last season with 16 victories, held Los Angeles scoreless on eight hits before turning the game over to the bullpen.

A club official said Batista would be further examined on Saturday.
