NEW YORK, N.Y. - Right-hander Chaz Roe and outfielder Smaily Borges were suspended for 50 games each Thursday under baseball's minor-league drug program.

Rose tested positive for an amphetamine, the commissioner's office said. Borges was penalized for refusing to take a drug test.

Both players are free agents, and their suspensions will start when they sign with a major league organization.

The 25-year-old Roe, taken by Colorado with the 32nd overall pick in the 2005 amateur draft, was traded to Seattle in December 2010 for infielder Jose Lopez. He went 0-7 with a 6.59 ERA in 10 starts and 23 relief appearances last year at triple-A Tacoma.

Borges, 27, played in the Chicago Cubs system for the last three years. He hit .233 in 133 at-bats last year at single-A Peoria.

Eight players have been suspended this year under the minor-league program.
