Serena was preparing 'runners up speech' before comeback win in US Open final

Sydney, Sep 10(ANI): Serena Williams, who won her fourth US Open title beating world number one Victoria Azarenka 6-2 2-6 7-5 in a gripping final on Sunday, has admitted she couldn't believe she won the final, as at one stage in the final set she was just two points from defeat when trailing 3-5.

In the first three-set final at the US Open since 1995, American fourth seed Williams joined her sister Venus and Steffi Graf as the only women to win Wimbledon, the Olympics and the US Open in the same year.

However, the 31-year-old admitted she felt beaten when Azarenka, whose only Grand Slam title came in Australia in January, went ahead in a high quality final set.

"I honestly can't believe I won," News.com.au quoted Williams, as saying after taking her fourth US Open title.

"I really was preparing my runners-up speech because I was thinking, 'Man, she is playing great'," she added.

Williams now has a staggering 15 Grand Slam titles to her name, and she became the second-oldest US Open women's champion in the Open era.

Australian Margaret Court was one month past her 31st birthday when she won the 1973 title. (ANI)
