It wasn't easy. Serena Williams had to fight off her nerves, the wind and the battle-tested grit of Victoria Azarenka to capture her fifth U.S. Open title with a 7-5, 6-7 (6), 6-1 victory on Sunday.
Once again, Azarenka proved she has an uncanny ability to lift her game and play her best against Williams, shocking the No. 1 by storming back from a 1-4 deficit to force a third set. From there, Williams stepped up her level, started serving bigger and better, and Azarenka couldn't respond.
"I felt almost disappointed with my year, to be honest," Williams said. "I felt like, yeah, I won the French Open, but I wasn't happy with my performances in the other two Slams, and not even making it to the quarterfinals of one. So I definitely feel a lot better with at least a second Grand Slam under my belt this year."
Though Williams now leads the head-to-head 13-3, her clashes with Azarenka have produced some of the best displays of women's tennis over the last two years. Theirs is the WTA's preeminent rivalry right now and that's full credit to Azarenka's competitive spirit.
"She really made it happen," Azarenka said after the match. "In that particular moment [in the third set], she was tougher. She was more consistent, and, she deserved to win. I wish I could do something better today. I felt like I had opportunities in the first set, as well. But it's OK. It goes that way. I did everything I could."
Azarenka added: "I lost to a great champion, but I'm still going to have my head up."
Williams now holds the longest span for a woman winning a major title, 14 years, dating to her 1999 U.S. Open title. Just a couple of weeks short of her 32nd birthday, Williams says she's feeling better than ever.
"I feel great," she said. "I have never felt better. I feel really fit. I can play a tournament like this, singles, doubles, with tough, tough schedules. ... I haven't felt like this in a number of years. I'm excited about the possibilities. I don't know what can happen. I just keep playing and do the best that I can."
