NEW YORK - No.19 seed Danielle Collins advanced to the fourth round of the US Open for the first time in her career after defeating No.40 Alizé Cornet 6-4, 7-6(9) under the lights on Arthur Ashe Stadium. Collins will now face No.6 seed Aryna Sabalenka for a spot in the quarterfinals.

Collins, 28, is part of a quartet of American women into the Round of 16, joining No.8 seed Jessica Pegula, No.12 seed Coco Gauff, and No.29 seed Alison Riske-Amritraj. Collins has paved her way into the second week with wins over Naomi Osaka, Cristina Bucsa, and Cornet. 

"Honestly, I'm having the time of my life. This is what we dream of as a kid, playing these night matches."

Why the veterans are thriving at the US Open

How the match was won: Collins broke Cornet in the fifth game of the opening set and was off to the races. With relentless baseline pressure, Collins quickly amassed 20 winners through the first eight games. Cornet played a tidy match, minimizing her errors and putting in a physical effort at the baseline, but the French veteran struggled to find any space to keep Collins at bay. Her only hope was to bait Collins into errors. But on this night, the American did not miss. 

The second rolled along with both women taking care of her serve. Only one break separated the two in the opening set, but neither woman was able to generate a single break point in the second set. 

"I think if we look at Alize's record she battles in every single match. When she goes down she doesn't go down easy. I knew I would have to follow the ball in to the net, be patient, and win points two, three, four times." 

In the tiebreak, neither player was able to break away. Collins saw her first match point at 6-5 saved with a strong first serve from Cornet, while Cornet could only watch as Collins erased a set point with a clean backhand winner to level at 7-7.

Collins saved a second set point with her 50th winner of the night. Collins' gutsy saves would be rewarded. On her second match point, Collins closed out the victory after 1 hour and 52 minutes. 

Stat of the match: Collins went unbroken in the match, facing down just one break point, while firing 52 winners to 29 unforced errors. Cornet hit 17 winners and just 9 unforced errors in the match. 

Up next: Collins faces a formidable foe in the next round. Sabalenka has won all three prior meetings, with two of those wins coming at the US Open, in the first round in 2018 and the third round just last year. Sabalenka has lost just one set to Collins and comes into the match off a 6-0, 6-2 win over Clara Burel. 

"We played a battle here a couple years ago," Collins said. It was three sets. She's a very powerful player. She really exposes people's weaknesses. But I think with how I'm playing, hopefully I can just have that laser focus and use my strengths, yeah, just keep going for it."
