Stephens, who has jumped more than 900 positions in the world rankings in a month, on Thursday reached her first major final, defeating No. It also will be Keys' first major final. It's the first all-American US Open final since 2002, when Serena Williams defeated Venus Williams. She's the fourth unseeded player to advance to a US Open final in the Open Era. She lost in the Australian Open final to her sister, Serena Williams, and the Wimbledon final to Garbine Muguruza.
