Mike Bryan may have won the point, but it proved an expensive one: At the US Open on Sunday, the American doubles player appealed a call made by a line ref, won the reversal, then turned his racket around to mimic a gun he pretended to fire at said ref. The gesture cost him an initial code violation for unsportsmanlike conduct, and an eventual $10,000 fine, reports CNN. "We won the point and the gesture was meant to be playful," Bryan said in a statement, while acknowledging that "given the recent news and political climate I understand how my gesture could be viewed as insensitive. I promise that I will never do anything like this again." Bryan and his brother, Bob, won their second-round match on Sunday. (More Mike Bryan stories.)
