Second-seeded Victoria Azarenka claimed the final spot in the quarterfinals with a three-set win over Ana Ivanovic, but Azarenka again wasn't up to her usual standards.
Rain may have changed the date for the women's final, but no one could change the eventual outcome as Serena Williams steamrolled to her fourth U.S. Open title.
Ana Ivanovic hadn't made it past the fourth round in a Grand Slam since winning the French Open and becoming No. 1 in 2008. She'll face Serena Williams, whom she never has beaten, in the quarterfinals.
The 19-year-old is one of the most anticipated American women players in years. After her three-set loss to Ana Ivanovic, she took solace in the fact that this is far from her last U.S. Open.
