Serena Williams won her fourth U.S. Open and the 15th major of her career, 6-2, 2-6, 7-5, on Sunday at Arthur Ashe Stadium by picking up her 10th career win against Victoria Azarenka.

Azarenka is now 1-10 all-time against Williams.

Azarenka may have lost, but she gave Serena everything she could handle. In the end, though, Williams prevailed in the first three-set women's final at Flushing Meadows since 1995.

The second set was the first that Williams dropped during the entire tournament, as the 30-year-old shows no signs of slowing down, with wins at Wimbledon, the U.S. Open and the London Olympics in 2012.

For Azarenka, the defeat was tough, as she was up 5-4 in the third set and serving for the match at 30-all but wasn't able to close the deal.

Even with the loss, she will remain the No. 1 player in the world when the 2013 season begins. But if she wants to keep her ranking, she'll likely need to improve her record against Serena.
