Miami Marlins prospect Kolby Copeland received a 50-game suspension for refusing to take an offseason drug test.

The 19-year-old batted .280 with no home runs and four stolen bases in 62 games with rookie ball and Low-A Jamestown. Baseball's drug programs at the major- and minor-league levels stipulate that refusal to submit to or comply with testing is considered a positive test for disciplinary purposes. A MLB spokesman told ESPN that six of the 105 minor league drug suspensions in 2012 were because a player refused to take a test.

His suspension will start at the beginning of this season. He is on the roster of Batavia of the New York-Penn League.
