Two minor leaguers drew 50-game suspensions from the commissioner's office for violating the Minor League Drug Prevention and Treatment Program. Both suspensions are effective at the start of the 2012 season.

Nationals righthander Zechry Zinicola, 26, was suspended for a second violation for a drug of abuse. The 2006 sixth-round pick out of Arizona State had his best season in 2011, tossing just 40 innings with a 44-13 strikeout-walk ratio while going 3-1, 2.01 between Double-A Harrisburg and Triple-A Syracuse. He's posted 49 saves and a 4.05 ERA in 293 career innings, allowing just 17 home runs.

Giants catcher Drew Stiner was suspended after testing positive for an amphetamine, falling under MiLB's performance-enhancing drug policy. Stiner, 19, signed as a 43rd-round pick out of Owasso (Okla.) High in 2011 and was a teammate of Orioles first-rounder Dylan Bundy. He signed in mid-August and has yet to make his pro debut.
