According to George A. King III of the New York Post, Major League Baseball is investigating Ivan Nova and minor league left-hander Wilkin De La Rosa for allegedly injecting each other with B-12 shots when they were teammates with Double-A Trenton last season.
B-12 is not on the banned substance list, however only licensed physicians are allowed to inject medication. Also, MLB wants to confirm that they were actually using B-12, and not something else. Yankees general manager Brian Cashman was not aware of the investigation while MLB spokesman Pat Courtney refused to comment. It's not known what sort of punishment either could face. Nova, 23, is scheduled to make his second major league start Sunday against the White Sox.
