The Mets issued a statement after a fan posted a video on Twitter of the mascot, known for his large baseball-shaped head and his oversize white hands, as he appeared to raise a finger while heading down a tunnel at the end of the game.

“We apologize for the inappropriate action of this employee,” the statement read. “We do not condone this type of behavior. We are dealing with this matter internally.”

A Mets spokesman declined to comment further.
