DENVER -- Daniel Stumpf said he rejoined the Phillies on Sunday with a clean conscience, maintaining his innocence and saying he has no idea how a performance-enhancing drug that first gained notoriety with East German athletes entered his system.
Stumpf, 25, tested positive in Spring Training for dehydrochlormethyltestosterone (DHCMT), which is an anabolic steroid better known as oral turinabol. He served the final game of his 80-game suspension Saturday. The Phillies activated him from the restricted list Sunday, optioning Severino Gonzalez and designating Mario Hollands for assignment to make room for him on the 25-man and 40-man rosters.
