O's prospect suspended 50 games

Double-A hurler Parker tests positive for second time

BALTIMORE -- The Commissioner's Office announced Thursday that Orioles prospect Brian Parker has been suspended 50 games for his second positive test for a drug of abuse in violation of the Minor League Drug Prevention and Testing Program.

Parker, a 19th-round selection in the 2007 First-Year Player Draft, is currently on Double-A Bowie's roster and will be suspended for the beginning of the regular season. The right-hander spent most of last season for Class A Frederick, where he posted a 4-3 record and a 4.31 ERA. Parker was promoted to Bowie toward the end of the season, registering a 3.60 ERA in two appearances.
