However, Bradley suffered many injuries. He required arthroscopic surgery in June 2001, and missed the remainder of the season. Though he required Tommy John surgery in October 2001 and missed the 2002 season as a result, he was nevertheless added to the 40 man roster following the season. He required surgery again in 2003. Bradley struggled when he reached Triple-A in 2005, and he was unconditionally released to make room on the roster for Zach Duke. Bradley went to camp with the Florida Marlins in 2006, but left after one day.
