PALM HARBOR, Fla. -- Justin Miller, a pitcher for four teams -- including the San Francisco Giants -- during a major league career that spanned seven seasons, has been found dead. He was 35.

Miller's death was confirmed Friday by his agent, Matt Sosnick. Miller's body was found Wednesday night, but the cause of death hadn't been released by the Pinellas County Sheriff's Office.

Miller pitched for the Blue Jays, Marlins, Giants and Dodgers from 2002 to 2010. He had a career record of 24-14 in 216 games.

Miller, who went to Torrance High in Southern California, spent most of 2000 and 2001 with the A's organization in AAA Sacramento of the Pacific Coast League. He was acquired in a trade with the Rockies in December 1999.

The Giants signed Miller in 2008 to a minor league contract. He made the Giants roster and appeared in 44 games out of the bullpen for the Giants in 2009.

The California native lived in Palm Harbor since 2002.
