The usage of amphetamines is banned by the Minor League Drug Prevention and Treatment Program.
The Dodgers farmhand, who turns 31 on Aug. 23, was in the midst of his 12th Minor League season. Prior to his suspension, Redman had 10 homers, 41 RBIs and 43 runs scored for the Triple-A Albuquerque Isotopes. His .332 batting average was among the best in the Pacific Coast League.
In 2003, he played in 15 Major League games for the New York Mets, the team that selected him in the 10th round of the 1999 Draft. He's also played in the Nationals and Mariners systems.
Redman is the second player in the Dodgers organization to receive a 50-game suspension in as many months. Andrew Lambo, a 21-year-old outfield prospect with the Chattanooga Lookouts in the Double-A Southern League, tested positive for a drug of abuse and was consequently suspended on May 1.
