While New York Yankees pitcher Cody Eppley wasn't looking, third baseman Eric Chavez decided to throw a ball to him.
And POW! Right in the head.
Good news for the Yanks as Eppley wasn't injured and just shook it off and continued to pitch.
Lesson to all you future big leaguers, always pay attention because you never know when Eric Chavez will give you a near concussion.
