San Francisco signed Uggla on July 21 after the Atlanta Braves released the struggling veteran on July 18. He went hitless in four games and 11 at-bats with the Giants, recording two errors in that span. That came after he hit .162 with a .472 OPS and recorded 11 errors in 48 games with the Braves.
Uggla's struggles this season and last mark a precipitous falloff from his performance from 2006 to 2012 with the Florida Marlins and Braves, when the second baseman put up an .813 OPS and averaged 30 home runs per season.
The 34-year-old is is earning a salary of $13 million this season and is due the same next season, which the Braves are responsible for paying. Uggla is now free to sign with any other team.
Outfielder Tyler Colvin, who was DFA'd at the same time as Uggla, was outrighted to Triple A Fresno on Friday.
