Over the weekend Serena Williams lost it after a line judge called a foot fault on her, a rarely used call by the way, that cost her match point and game.
Now she has to pay.
Right now the fine sits at $10,000.00, less than 3% of the $350,000 she earned by making it to the finals, but more fines and a possible suspension could be in her future. The line judge says she felt threatened after claiming Serena said she would "kill her".
