NEW YORK -- Clinton Hollon, the Blue Jays' No. 13 prospect, was suspended 50 games on Friday after testing positive for a banned substance.
The Office of the Commissioner of Baseball said Hollon, a right-hander with Class A Lansing, received a 50-game ban without pay after testing positive for an amphetamine, a stimulant in violation of the Minor League Drug Prevention and Treatment Program.
The suspension is effectively immediately, ending Hollon's season.
The 20-year-old was Toronto's second-round pick in the 2013 Draft out of Woodford County High School in Kentucky. He missed all of last season while recovering from Tommy John surgery and was 2-2 with a 3.18 ERA in nine starts for Class A Short Season Vancouver before earning a promotion to Lansing on Aug. 5.
In the Midwest League, Hollon was 1-1 with a 4.05 ERA in three starts, striking out five over 13 1/3 innings. He last pitched on Sunday at Kane County, although his best outing came in his Class A debut, when he held Wisconsin to one hit over seven frames for the win.
Amphetamines are considered a stimulant and a performance-enhancing substance by the Major League Baseball's Joint Drug Prevention and Treatment Program. Minor Leaguers who test positive for PEDs are subject to at least a 50-game suspension for their first violation, with many this season getting 80-game bans.
Major League Baseball has issued 79 suspensions to 78 players this year for violations of the Minor League drug program.
