A pair of Double-A righthanders received 50-game suspensions without pay, according to a press release issued by the commissioner's office today.

The Reds' Luis Atilano, who made one start for Triple-A Louisville and one for Double-A Pensacola, both in April, will sit out 50 games after a second violation for what Major League Baseball deems a drug of abuse. The 27-year-old signed with Cincinnati as a minor league free agent in December and has spent most of the season on the disabled list.

Double-A Portland's Marco Duarte, whom the Red Sox acquired in December when they traded Rule 5 pick Marwin Gonzalez to the Astros, tested positive for an amphetamine. The 25-year-old righty reliever logged 10 strikeouts, nine walks and 15 hits allowed in 17 innings for Portland, but had a much more aesthetically-pleasing 17-4 K-BB ratio with high Class A Salem through mid-May.
