Madison Keys put on a commanding performance to advance to the first Grand Slam final of her career, defeating fellow American CoCo Vandeweghe, 6-1, 6-2, Thursday night in Arthur Ashe Stadium.

Keys will next face another American, unseeded Sloane Stephens, on Saturday afternoon for the 2017 US Open women’s singles title.

Keys and Vandeweghe were meeting for the third time as professionals, all three meetings having come inside this summer swing; Keys was victorious in the final at the Bank of the West Classic in Stanford in straight sets, and prevailed in three at the Western & Southern Open in Cincinnati in August.

On Saturday, Stephens and Keys — a pair of pals in their early 20s — will meet in the first Grand Slam title match for each and the first all-American women’s final at Flushing Meadows since 2002.
