Detroit, MI -- (Sports Network) - The Detroit Tigers announced on Thursday that they have declined to exercise the 2009 option on the contract of shortstop Edgar Renteria, making the veteran a free agent.

Renteria batted .270 with 10 home runs and 55 RBI in 138 games last season, his first for the Tigers. He was acquired from Atlanta in a three-player deal on October 29, 2007.

The 33-year-old Renteria, who just completed his 13 big league season, has also played for Florida, St. Louis, Boston and Atlanta, and owns a career .290 batting average with 127 homers, 817 RBI and 280 stolen bases in 1,860 games. He has also participated in 55 postseason contests and had the game-winning hit in the bottom of the 11th inning in Game 7 of the 1997 World Series with Florida.

In addition, the Tigers outrighted the contracts of pitcher Gary Glover and catcher Dane Sardinha to Triple-A Toledo and retained Jeff Jones as the bullpen coach.

Glover was 1-1 with a 4.43 earned run average in 18 games with the Tigers in 2008, while Sardinha appeared in just 17 games for the Tigers and batted .159 with three runs batted in.

Both have elected to become free agents.

The Tigers also re-hired bullpen coach Jeff Jones, while Bruce Tanner has been promoted to major league scout.
