Peoria Chiefs pitcher Robert Hernandez has been
suspended for 50 games by the baseball commissioner's office after
testing positive for a steroid under the sport's minor league drug
program.

The 19-year-old right-hander was 8-9 with a 4.34 ERA in 20 starts last season with Peoria of the Midwest League and currently
is assigned to the same club. He tested positive for stanozolol.

The commissioner's office said that starting with Hernandez, it will identify the specific substances players test positive for under the minor league plan. It does not announce specific
substances under the major league testing program, which is subject
to collective bargaining with the players' association.

Hernandez became the third player suspended this year under the
minor league program.
