Padres All-Star outfielder Urena suspended

NEW YORK -- Padres Minor League All-Star outfielder Jose Urena, former San Diego prospect Henry Charles and veteran right-hander Adam Reifer were suspended Thursday after each tested positive for performance-enhancing substances.

The Office of the Commissioner of Baseball said Urena received an 80-game suspension without pay following a positive test for Nandrolone, while Charles and Reifer were given 76-game bans for Nandrolone and Ostarine, respectively.

Urena's suspension is effective immediately, while Charles and Reifer -- both free agents -- will need to serve their punishments upon signing with another Major League team.

Urena, 21, hit .258 with seven homers, 45 RBIs and eight stolen bases in 63 games as a Northwest League All-Star for the Padres' Class A Short Season affiliate in Tri-City last season. The right-fielder has hit .245 with 28 home runs and 136 RBIs in 232 career Minor League games since signing with the Padres as a free agent out of Mexico in August 2011.

Charles, who was teammates with Urena at Tri-City last season, was released by San Diego on April 2 after hitting .188 with a pair of homers and 23 RBIs in 63 games in 2015. The 22-year-old signed with the Padres in 2010 and has hit .244 with 18 homers and 125 RBIs in 303 career Minor League games.

Reifer, 29, was in Spring Training camp with Tampa Bay last month but was released on March 25 after going 1-0 with a 6.75 ERA in four spring games at Major League camp. The right-hander spent last season in the Mexican League, going 1-2 with a 1.33 ERA for Yucatan after pitching for Triple-A Fresno in 2014. Originally drafted by the Cardinals in 2007, the three-time Minor League All-Star is 19-20 with a 3.68 ERA and 329 strikeouts in 349 1/3 career Minor League innings since 2008.

Nandrolone, commonly sold as Deca-Durabolin, is an anabolic steroid used to promote muscle growth, bone density and red blood cell production. It's considered a Schedule III controlled substance.

Ostarine, also known as Enobosarm, is used to help build muscle strength and stamina during workouts. SARMs were also banned by the World Anti-Doping Agency in 2008.

The Commissioner's Office has suspended 34 players this year for violations of the Minor League Drug Prevention and Treatment Program.
