NEW YORK -- Daniel Muno, the Mets' No. 17 prospect, and Giants Minor League pitcher Luis Rojas were each suspended 50 games on Friday after testing positive for banned steroids.
Muno, the Mets' No. 1-ranked Minor League shortstop, received a 50-game suspension after testing positive for a metabolite of Drostanolone, an anabolic steroid sometimes used by bodybuilders.
Rojas tested positive for Stanozolol, a synthetic anabolic steroid commonly sold under the name Winstrol.
Both suspensions are effective immediately.
Muno, a 23-year-old out of Fresno State, is hitting .283 with five homers and 23 RBIs for Class A Advanced St. Lucie in the Florida State League. The switch-hitter was New York's eighth-round pick in last year's Draft and earned MiLB.com Organization All-Star status after hitting .355 with two homers, 24 RBIs and nine steals as a New York-Penn League All-Star with Class A Short-Season Brooklyn.
Muno is the third St. Lucie Met to receive a ban this season following Dock Doyle and Scott Moviel, who were suspended for drugs of abuse on Feb. 9.
Rojas, a right-handed reliever originally signed by the Mets in 2006, owns a 3.38 ERA with nine strikeouts in eight innings for Class A Advanced San Jose in the California League. He spent the previous five seasons with the Mets at the Class A level.
Major League Baseball has now suspended 42 players this year for violations of the Minor League Drug Prevention and Treatment Program.
