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.

The Cleveland Guardians have identified a fan who "crossed the line" while taunting Boston Red Sox outfielder Jarren Duran during Sunday afternoon's game at Progressive Field, the team announced. The fan left the stadium immediately after the incident, but the Guardians are aware of the person's identity, according to Cleveland.com.

Duran said a fan in the front row Sunday near the Red Sox dugout in Cleveland said “something inappropriate” to him.
