Boston Red Sox outfielder Jarren Duran's encounter with a heckler on Sunday in Cleveland led to the fan's ejection and an apology from the Guardians.

A Cleveland Guardians fan ran his mouth during a recent game against the Boston Red Sox, and it may have gotten him in some serious trouble. The fan reportedly said something to left fielder Jarren Duran that “ crossed the line ” during the game.

Duran stayed on the top step of the dugout and glared at the fan, and his teammates and coaches kept him away as umpires and security personnel gathered to handle the situation.
