Serena Williams overcame a battling Victoria Azarenka to win her fourth US Open with a 6-2, 2-6, 7-5 victory at Flushing Meadows.
24 hours after a tornado had forced the postponment of the women's singles final Victoria Azarenka and Serena Williams stepped onto Arthur Ashe Stadium to battle it out for the US Open title.
Williams had won nine out of her 10 previous matches against Azarenka and looked as though she would cruise to her 16th Grand Slam title when she took the first set 6-2.
However, Azarenka showed why she is world number one by bravely battling her way back into the match, taking the second set 6-2 as the women's final of a US Open went to a third set for the first time since 1995.
Azarenka hadn't lost a three set match all year and had her American opponent on the back foot for much of the decider, moving into a 5-3 lead at one point.
However, the Australian Open champion couldn't serve out the match as Williams broke back, much to the delight of the partisan crowd.
The next time Azarenka served it was to stay in the match.
However, Williams wasn't to be denied as Azarenka sent a backhand long to hand her opponent a fourth US Open title.
The 6-2, 2-6, 7-5 win completes a fantastic summer for Williams after she won Wimbledon and Olympic gold in the women's tennis tournament.
Earlier in the day Novak Djokovic had set up a mouth watering men's final against Andy Murray after battling back from a set down to beat David Ferrer.
Ferrer took the first set 6-2 but couldn't keep up with the world number two in the next three, the defending champion eventually claiming the spoils 2-6, 6-1, 6-4, 6-2.
