New York: Local lass Madison Keys dominated CoCo Vandeweghe 6-1, 6-2 to reach her first Grand Slam final.
The No 15 seed will face unseeded Sloane Stephens on Saturday in the first US Open final between American players since Serena Williams beat Venus Williams in 2002.
Keys had no problem with the No 20 seed Vandeweghe or with an upper right leg injury that caused her to call the trainer to be taped midway through the second set.
Madison Keys easily took the first set 6-1. She raced to a 5-0 lead and won 19 of the first 22 points, eventually winning the set in 23 minutes.
Earlier, Sloane Stephens reached her first Grand Slam final, edging Venus Williams 6-1, 0-6, 7-5 in the first of two all-American semifinals.
Stephens became just the fourth unseeded player to reach the US Open women's final in the Open era, which began in 1968, and the first since Roberta Vinci in 2015.
The third set was tense tennis after two lopsided ones, with Stephens continuously running down balls to win long rallies.
