USTA announced that it had fined Serena Williams $10,000 for a profane tirade. But that isn't the end of it.

Williams' tirade against a lineswoman who called her for a foot fault Saturday night in her semifinal match against Kim Clijsters may have gotten her into deeper trouble beyond the penalty point assessed that cost her the match. As taken from CBS replays of the tirade, Williams said at one point: "If I could, I would take this f---ing ball and shove it down your f---ing throat."
