(CBS) White Sox minor leaguer Nicholas Blount and Cubs minor leaguer Eliot Soto have each been suspended for 50 games by Major League Baseball for violating baseball’s drug prevention and treatment program.

The suspensions will start at the beginning of next season. 

Blount, a right-handed pitcher for the rookie-level Great Falls Voyagers of the Pioneer League, tested positive for an amphetamine. 

Soto, a shortstop for the Single-A Daytona Cubs of the Florida State League, was banned for his second offense. 

Blount was drafted in the ninth of round of this year’s draft. He went 4-4 with a 3.18 ERA in 16 games this season. 

Soto, a 15th-round pick in 2010, batted a combined .219 in 84 games at Single-A Daytona and Double-A Tennessee in 2013.
