Rockies' outfielder Clark suspended
The suspension of Clark is effective immediately.
Clark, currently a member of Class A Advanced Modesto of the California League, was selected by the Rockies in the sixth round of the 2006 First-Year Player Draft.
The 23-year-old Manatee Junior College product ranked second on Class A Short-Season Tri-City in homers as a rookie in 2007 before batting .262 with 17 home runs, 76 RBIs and 22 steals for Class A Asheville in the South Atlantic League last season.
His 76 RBIs with the Tourists ranked him 11th in the league.
Clark's suspension comes one day after Brewers' Minor League pitcher Pedro Lambertus was banned for 50 days after testing positive for metabolites of Boldenone.
