More details have been revealed as to why the New York Yankees placed starting pitcher Domingo Germán on the restricted list Thursday.

According to SNY's Andy Martino, Germán "grew belligerent" while in the Yankees clubhouse Tuesday evening, with witnesses determining him to be under the influence of alcohol and not in control of his emotions. There is reportedly no indication of an altercation between the right-hander and any other individual.

Germán reportedly flipped over a couch and smashed at least one television during the incident while teammates and staff tried to calm him down, according to the Wall Street Journal's Lindsey Adler. He also reportedly had a verbal altercation with Yankees manager Aaron Boone and other unnamed people in the clubhouse before teammates sent him to the team's sauna room. Germán was then taken to the team's nap room before Tuesday night's game with security stationed outside the door.
