Serena Williams went ballistic on a line judge at the U.S. Open after the judge awarded a point to her opponent that cost Serena the match...
In the first game of the second set after Serena fired a blistering forehand across the net, she screamed out 'Come On!' before her opponent Samantha Stosur got a chance to hit the call. The judge called Serena's yelling a hindrance and awarded the point to Stosur who went on to win the match.
Later Serena told the line judge,
"You're a hater. And you're unattractive inside.
If you ever see me walking down the hall, look the other way. Cause you're out of control. You're out of control.''
