An associate that worked with suspended San Francisco Giants left fielder Melky Cabrera has been banned from "clubhouses or all non-public areas" of all 30 major-league stadiums, reports ESPN.com.
Juan Nunez is said to have schemed to explain Cabera's positive test for testosterone by creating a fictitious supplement and advertising it on a fake website. Cabrera was suspended 50 games for the positive test and will miss the rest of the regular season.
Major League Baseball has not confirmed reports of Nunez's involvement in the plot. The directive that was handed out tells clubs to ban Nunez from "non-public areas" and to avoid dealing with him at all.
