Renteria leaves with tightness in groin

SAN FRANCISCO -- Giants shortstop Edgar Renteria left Friday night's series opener against the Colorado Rockies after two innings with tightness in his groin.

Renteria, who is listed as day-to-day, missed two games last week with discomfort in his left shoulder.

Renteria drew a first-inning walk and slid into second base in an attempt to break up a double play, then stayed in the game for the second inning and handled a routine Clint Barmes grounder.

But when the Giants took the field for the third inning, Juan Uribe moved from second base to shortstop, Mark DeRosa switched from left field to second base and John Bowker entered the game to play left.
