Alizé Cornet (FRA) / Alicja Rosolska (POL) v Abigail Spears (USA) / CoCo Vandeweghe (USA) 
CoCo Vandeweghe is bidding to become the first player since Lindsay Davenport, in 1999, to win both the women's singles and doubles tournaments in the same year. Davenport is currently acting as coach to Vandeweghe's opponent in Sunday's final - Madison Keys.
CoCo Vandeweghe previously made the Stanford final in 2012, losing to defending champion Serena Williams. That meeting also marks the last time two Americans competed in the final in Stanford.
Madison Keys is enjoying her best showing at Stanford, having previously made two last 16-exits. The American lost to Vera Dushevina at that stage in 2013 and again to Ajla Tomljanovic two years later.
Other than Serena Williams - champion in 2011, 2012 and 2014 - the last American woman to win in Stanford was Lindsay Davenport, in 2004. Three of the last eight beaten finalists in Stanford have been American - Venus Williams losing in 2009 and last year, with CoCo Vandeweghe beaten in 2012.
The last five all-American finals in Stanford have featured a Williams sister (Venus losing in 1998, 1999 and 2004, and winning in 2000; Serena winning in 2012).
CoCo Vandeweghe is yet to drop a set at this year's tournament, beating two seeds (Anastasia Pavlyuhenkova and Catherine Bellis). Madison Keys has dropped one set, also beating two seeds - Lesia Tsurenko and Garbiñe Muguruza.
Three of the last four Stanford finals have gone to three sets - Serena Williams' victory over Angelique Kerber in 2014 being the exception.
The Americans are meeting for the first time.
This will be the third successive Stanford tournament where the top seed has failed to win the event.
