(CHICAGO, IL) -- A man ran on the field at Wrigley Field in the seventh inning Friday, stripped, stood on the mound and made an obscene gesture.

The Chicago Cubs' Eric Young had just singled to lead off the seventh when the man run onto the field from near the visiting team's dugout. He stopped shy of the mound, took off his shorts and shirt, and then stood on the mound.

Chicago's Ricky Gutierrez, who was at the plate, was seen laughing along with several other players.

The man was taken away by security guards, who grabbed him by his hair and rushed him off the field and through the stands, still naked.
