Victoria Azarenka will meet Serena Williams in the women's final at the US Open, after both came through their respective semi-finals at Flushing Meadows in New York on Friday.
Earlier in the day, Bob and Mike Bryan won the men's doubles title, pocketing a record 12th Grand Slam title as a partnership.
The Arthur Ashe Stadium crowd witnessed history on Friday.
Bob and Mike Bryan defeated Radek Stepanec and Leander Paes to win the US Open men's double title in straight sets.
It is the American duo's twelfth Grand Slam crown. The Bryan brothers are now the most successful doubles team in the Open era after they surpassed the record of Todd Woodbridge and Mark Woodforde.
World number one Victoria Azarenka took on 2006 champion Maria Sharapova for a place in the final.
Sharapova dominated the first set, eventually taking it 6-3. Azarenka fought back in the second, forcing the match in to an intriguing decider.
And the momentum remained with the 23-year-old from Belarus as she broke the Russian to seal a spot in her first US Open final.
Fourth seed Serena Williams met Italy's Sara Errani in the other semi-final and it was a one-sided encounter from the start.
Willliams raced to a 5-0 lead in the first set, breaking serve twice, and closed out for 6-1 inside half an hour.
Errani, who gave impressive performances in the fourth round and quarters, showed a little more fight in the second set.
But she couldn't contain Williams, who secured a seventh appearance in a US Open final with a 6-1, 6-2 victory.
Serena has a 9-1 career winning record against Azarenka and will be hoping for a fourth US Open title following her London triumphs at Wimbledon and the Olympics.
