Unemployed outfielder Marlon Byrd, who was released by the Boston Red Sox last Tuesday, has been suspended for 50 games by Major League Baseball after testing positive for Tamoxifen, a banned substance.

Byrd was traded to Boston by the Chicago Cubs in April for Michael Bowden, with the agreement that the Cubs would pay most of his $6 million salary for 2012, but was largely a disappointment for a Red Sox team that was desperate for help in the outfield. After being released from the team, he had received some interest from the Cleveland Indians and Kansas City Royals, which will most likely subside with this latest news.

His .035 ISO this season shall forever be tainted.

Update: I completely forgot about Byrd’s association with Victor Conte’s SNAC brand of supplements.
