NEW YORK (AP) — Feeling wronged again at the U.S. Open, Serena Williams couldn’t let it go.

“That’s totally not cool,” she shouted at the umpire. Then, a few minutes later, she told her, “You’re a hater, and you’re just unattractive inside.”

Problem was, the real trouble for Williams was standing on the other side of the court.

Sam Stosur pushed the 13-time Grand Slam champion all over Arthur Ashe Stadium on Sunday and took what she wanted, along with what the umpire gave her, winning the U.S. Open in a result that was as surprising for who won as how lopsided it was.

The ninth-seeded Australian won her first Grand Slam title with a 6-2, 6-3 dismantling of No. 28 Williams, the three-time U.S. Open champion who hadn’t lost a set en route to the final.

She lost two quick ones to Stosur. And, for the second time in three years, Williams did not leave Flushing Meadows quietly.

This time, the drama began when Williams, down a set and facing break point in the first game of the second, flushed a forehand deep to Stosur’s backhand side and screamed out ‘C’mon!’ — figuring she had hit a shot that Stosur wouldn’t reach. But Stosur stretched out and got a racket on the ball and the umpire, Eva Asderaki, called Williams for a hindrance, awarding the point, and thus the game, to Stosur.
