Detroit Tigers farmhand Timo Perez, who helped the Mets reach the World Series back in 2000, was among four minor league players who were suspended by the commissioner's office Tuesday for violating the league's drug policies.

Perez got a 50-game suspension for testing positive for Ritalinic Acid and Methylphenidate. Both drugs are used to treat attention deficit disorder. Perez has more than 600 big league games under his belt but has been in the minors since 2007; the 36-year-old hit .304/.344/.410 at Triple-A Toledo this season. (Note: The Tigers released Perez subsequent to the suspension's announcement, according to the International League transactions page.)

Athletics outfielder Mitch LeVier, a ninth-round pick in 2008 out of Fullerton (Calif.) JC, was suspended for 50 games for a second violation for using a drug of abuse. LeVier hit .218/.266/.395 with 15 home runs at high Class A Stockton this season.

Two minor league free agents also were suspended 50 games for performance-enhancing drugs: catcher Oscar Rodriguez, most recently of the Pirates organization, and righthander Kelvin Santana, who pitched in the Astros' Dominican Summer League club this past summer.

All the suspensions begin next season or as soon as the free agents are signed by a new organization.
