New York: World number one Serena Williams enters the US Open as a heavy favorite to defend her title, but second-ranked Victoria Azarenka leads a host of rivals looking to dethrone her.
Williams is seeking her 17th Grand Slam singles crown and fifth US Open title, which would move her one shy of Chris Evert's Open-era record for most titles at the year's final major event on the Flushing Meadows hardcourts.
"I'm definitely prepared. I'm definitely ready for New York," Williams said. "I definitely had more matches than I could want, but I'm definitely prepared for the US Open."
