OAKLAND, Calif. (AP) _ Cincinnati shortstop Barry Larkin left Tuesday's game against the Oakland A's when he appeared to aggravate a sore abdominal muscle while fielding an infield hit.

The 40-year-old Larkin was making just his second start in a week because of the injury. He cut across the diamond to field a slow hopper hit by Estaban German and didn't make the throw.

Larkin, in his 19th season with the Reds, went down on his knees, but eventually walked off the field. He has announced this is his last season.

Larkin singled in his first at-bat, then hit a three-run homer in the second inning off former Cy Young Award winner Barry Zito.

Larkin flied out to right in his third at-bat before departing.

No further information about the injury was available.
