Union concludes Cabrera's agents unaware of scheme

Brothers Sam and Seth Levinson, the heads of ACES Inc., were probed by the Major League Baseball Players Association after MLB's investigations department discovered the attempt to concoct evidence. Cabrera, the San Francisco Giants outfielder who was the MVP of the All-Star game, was suspended 50 games in August after testing positive for testosterone.

"After a thorough investigation, we concluded none of the ACES principals were involved in or had knowledge of the Cabrera scheme," union head Michael Weiner said Tuesday from Los Angeles, where he was attending agents' meetings. "We also concluded there was an issue with supervision of employees."

Weiner said action had been taken against the Levinsons, but would not be more specific, and said ACES remains eligible to represent all players.

'We are pleased to have been cleared of wrongdoing by the players' association after its thorough investigation, and we greatly appreciate the support we received from our players," Seth Levinson said in a statement.

The union, whose conclusions were first reported by Yahoo!, denied the application for limited agent certification of Juan Nunez, whom ACES said was a consultant. Nunez took responsibility for fabricating a website that Cabrera was intending to rely on in the union's grievance to overturn the suspension.

Union general counsel Dave Prouty said Nunez was indefinitely barred from certification as an agent of any kind. Limited certification allows agents to deal with players but does not permit them to negotiate with teams.

The union also turned down the application for limited certification by Juan Nunez's brother, Tirzon Nunez, but that denial was made without any restriction on reapplication for any type of certification, Prouty said.
