Tabata exits early with discomfort in left groin

PITTSBURGH -- Jose Tabata was removed from Saturday night's game after apparently tweaking his left-groin muscle while running the bases in the bottom of the fifth.

The left fielder had doubled for the Pirates' third run of the inning and felt the tweak in the groin area as he rounded first base, according to manager Clint Hurdle.

Tabata stayed on the bases and scored to make it 4-0 over the Brewers on a single by Travis Snider.

When the inning concluded, the Bucs made a series of defensive changes to allow for Tabata's departure. Snider switched from right field to left, Garrett Jones moved from first base to right field, and Gaby Sanchez went in to play first and replaced Tabata as the leadoff hitter in the lineup.

The club attributed the cause of Tabata's removal to "discomfort in the left groin" and said he was undergoing further evaluation. The Pirates anticipate being able to update his condition on Sunday morning.
