Hotheaded tennis star Serena Williams has been fined $2,000 for her outburst during yesterday's U.S. Open final. Video shows Williams berating the chair judge during a break in the second set, telling the official, among other things, "If you ever see me walking down the hall, look the other way, because you're out of control... You're totally out of control, you're a hater, and you're unattractive inside." Reuters reports that Williams has refused to apologize for the threats and insults, explaining that they were made in the heat of the moment. Also, this is America last time she checked—many brave soldiers have given their lives to defend her right to be rude.

Williams is still on a two-year probation following a 2009 temper tantrum at the U.S. Open, when she told a line judge, "I swear to God I’m [expletive] going to take this [expletive] ball and shove it down your [expletive] throat, you hear that? I swear to God.” After reviewing the incident, the U.S. Open tournament referee ruled that the incident did not violate her probation, which is good news for Williams and the USTA, which needs high-wattage stars like Williams to make a buck. Had Williams's outburst been deemed a "major" violation of the Grand Slam Code of Conduct, she would have been prohibited from participating in the U.S. Open next year.

And it turns out the $2,000 fine was not the biggest fine at this year's U.S. Open. The LA Times reports that men's doubles players Mike Bryan was fined $10,000 for an "off court" incident after he and brother Bob Bryan lost in the first round. A U.S. Open official refused to disclose the nature of the incident, because Mike Bryan can still appeal the fine.
