MLB Network analyst Mitch Williams was ejected Saturday from a baseball game for 10-year-olds after a profanity-laced tirade in which he called an umpire a "motherfucker" in front of the children, observers tell us.

Williams coaches his son's 10U Jersey Wild team, which was participating in a Ripken Baseball tournament in Aberdeen, Md. We've confirmed through several sources that Mitch Williams—who was once tossed from his daughter's youth basketball game for cussing at the ref—had complained about numerous calls throughout the game, ranging from balls and strikes to a close play at the plate that ended a Jersey Wild rally. This led to repeated arguments with umpires on the field.

One umpire finally confronted Williams after the former MLB pitcher shouted something to a parent in the stands about getting that umpire fired. The confrontation sparked a face-to-face argument that, one parent told us, was "just like the major leagues." Two different observers told us Williams had to be physically separated from the umpire by other coaches. Williams then refused to leave the field, causing a 10-minute delay in play; as a result of his antics, he was initially banned from the tournament.
