Defending champion Serena Williams defeated Victoria Azarenka in a rematch of the previous year's final, 7–5, 6–7(6–8), 6–1 to win the women's singles tennis title at the 2013 US Open. It was her fifth US Open singles title and her 17th major singles title overall. For the second consecutive year, Williams lost only one set during the tournament, again to Azarenka in the final.[1] [2]
This was the last major main draw appearance for former world No. 3 Nadia Petrova, who lost to Julia Glushko in the first round.
