16. Sean Rodriguez (2012)
Rodriguez is a longterm MLB veteran. Six different franchises signed the utility player throughout his career. A native of Miami, he usually maintains a calm temperament. But that went out the window in 2012 when he punched a locker. He missed a month of action because he broke his hand. Needless to say, this didn’t please his coaches or his teammates because it left them in the lurch.

Manager Joe Maddon publically criticized the player (via Tampa Bay Times). “He obviously was upset about his actions and how inappropriate they were. He’s always been an accountable fellow,” Maddon said. “But you just can’t do things like that.” The reality is that Rodriguez is just one of many baseball players to lash out. One thing is for certain; he won’t be the last.
