NEW YORK -- Even Mr. Met is frustrated with the team's disappointing start.

New York's beloved mascot flashed his "middle" finger at a fan during Wednesday night's 7-1 loss to the Milwaukee Brewers, and the team says the employee won't work in the costume again.

A person tweeted video of the incident, which soon went viral online, and the club quickly issued a statement.

The loss puts the Mets five games under .500 and nine games back of the Nationals in the NL East, pending the result of Washington's game in San Francisco on Wednesday, CBS Sports reports. It also gives the Mets a losing record in May after going 10-14 in April to start the season.
