The commissioner's office today announced 50-game suspensions for two minor league players following their violations of the game's drug prevention and treatment program.

Double-A Tennessee utilityman Matt Camp failed a second test for a "drug of abuse" to earn his suspension. A Cubs 13th-rounder from North Carolina State in 2006, he batted .169/.289/.246 in 65 at-bats for the Smokies. The 27-year-old Camp also appeared in 58 games for Triple-A Iowa, batting .209/.259/.262 in 187 at-bats. He plays center field, shortstop and second base.

Righthander Adam Osteen spent about two weeks under contract with the Diamondbacks this summer, but now he'll have to sit out 50 games before he can suit up for another organization. The 23-year-old tested positive for Methasterone and metabolites of Methandienone, according to an MLB press release. A product of Southeastern (Fla.), Osteen played in the independent Frontier and Pecos leagues this season prior to signing with Arizona. He appeared in five games for short-season Yakima, pitching 6 1/3 innings and allowing seven hits, two walks and six runs.
