Here is a player profile, a look at the form and records of American Madison Keys and compatriot Sloane Stephens ahead of Saturday's US Open final (prefix number denotes seeding)
Keys, armed with one of the most powerful forehands on the tour, dropped just three games to knock out compatriot CoCo Vandeweghe in the semi-finals.
The 22-year-old, who missed the first two months of the season with a wrist injury, has peaked at the right time after lifting the title in Stanford last month.
Stephens, who is returning from a long-term foot injury, has continued her remarkable revival at the US Open after reaching the semi-finals in Toronto and Cincinnati last month.
The 24-year-old produced a stellar performance to knock out two-time champion Venus Williams to reach her maiden grand slam final.
