US Open Tennis 2021 Results: Thursday Winners, Scores, Singles Draw Update

Leylah Fernandez and Emma Raducanu form the unlikeliest of U.S. Open women's singles final matchup after semifinal victories on Thursday night. 

The pair of teenagers played well above their current rankings in wins over a pair of seeded players. 

Fernandez won her fourth straight match against a ranked foe in a three-set battle against No. 2 seed Aryna Sabalenka.

Raducanu did not need to go the distance versus No. 17 seed Maria Sakkari. The 18-year-old British player turned in one of the most dominant performances of the tournament inside Arthur Ashe Stadium.

Fernandez and Raducanu will face off on Saturday at 4 p.m. ET for the final Grand Slam title of the tennis season. 

Thursday U.S. Open Results

Leylah Fernandez def. No. 2 Aryna Sabalenka, 7-6(3), 4-6, 6-4

Fernandez added the second-seeded player in the women's singles draw to the list of high-profile stars she has eliminated in New York.

The 19-year-old Canadian had an answer for everything Sabalenka threw at her over the course of three sets. 

Fernandez's stats were not as impressive as the ones produced by Sabalenka in the first set, but she came up with points when it mattered most in the tiebreak.

Sabalenka held a 21-9 advantage in winners in the first set, but Fernandez only committed six unforced errors.

Fernandez won the final four points in the opening set tiebreak to take the first stanza.

Sabalenka bounced back in the second set thanks to a break in the ninth game.  

But the No. 2 seed committed 12 more unforced errors and delivered three fewer winners in the final frame. 

The last of those unforced errors occurred on the last point of the match, and Sabalenka failed to win a single point on her final service game.  

Fernandez has now beaten four seeded players in a row. Two of them, Naomi Osaka and Angelique Kerber are Grand Slam champions. The other two, Sabalenka and Elina Svitolina, are top-five players in the world. 

Emma Raducanu def. No. 17 Maria Sakkari, 6-1, 6-4

Raducanu produced her best performance of the tournament against Sakkari.

The 18-year-old was unstoppable in the first set, as she held the Greek player to a single game victory. 

Raducanu went 2-of-3 on her first-set break-point opportunities, won 57 percent of her receiving points and only committed eight unforced errors. 

Sakkari, however, committed 17 unforced errors and failed to take advantage of any of her seven break-point chances. 

Raducanu fended off the late second-set surge from Sakkari to close out the contest in just under 90 minutes. 

The victory from Raducanu set up the first women's singles final between two teenagers since 1999, when Serena Williams played Martina Hingis.
