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)
15-Madison Keys
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.
Sloane Stephens
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.
