Coco Gauff advanced to the semi-finals of the US Open on 9 September 2026 with a dramatic 2-6, 7-6 (7), 6-2 victory over fifth-seeded Mirra Andreeva, recovering from a disastrous opening set and two match points in the second-set tiebreaker to extend her winning streak. The fourth-seeded American's comeback at Arthur Ashe Stadium ended her opponent's bid to reach the final and set up a semi-final clash with second-seeded Elena Rybakina.
Gauff's path to victory was far from the polished performances that had defined her earlier rounds. She dropped the opening four games, surrendering the first set in just 26 minutes and ending a streak of 20 consecutive sets won that had stretched back nearly a month. She committed 12 double faults and 42 unforced errors, predominantly from a forehand that repeatedly misfired. Facing elimination twice during a tense second-set tiebreaker, Gauff found herself one point from defeat before clawing back to force a decider.
The turnaround proved decisive. Once the third set began, Gauff's confidence returned and she dominated the final frame 6-2, extending her overall winning streak to 10 consecutive matches.
How did Gauff reach the quarter-finals?
Gauff's earlier rounds at the US Open had been marked by commanding performances. She defeated fellow American Iva Jovic 6-1, 6-4 in the fourth round in one hour and 32 minutes, extending her unbeaten streak through the tournament without dropping a single set. That victory showcased her most polished play of the fortnight, with 18 winners to Jovic's nine and only 15 unforced errors compared to her opponent's 30.
The 22-year-old's dominance in that match reflected a transformation in her approach to the game.
"The biggest difference in the way I've been playing is just trying to play with no regrets," Gauff said after defeating Jovic. "I think I have a lot more fun and success playing like this."Her confidence had been built on work with biomechanics expert Gavin MacMillan over the past year, a partnership that yielded semi-final runs at Wimbledon and a title in Cincinnati before her arrival in New York.
Jovic, the 18-year-old Los Angeles native seeded 14th, had arrived as one of the brightest prospects in American tennis. She had reached the Australian Open quarter-finals in January and posted fourth-round showings at both Roland Garros and Wimbledon, making her the youngest American to reach the second week at three majors in a single season since Venus Williams in 1998. On the Saturday before her loss to Gauff, she had battled back from 2-4 down in the deciding set to defeat breakout star Alexandra Eala 7-5, 3-6, 7-5 in a grueling three-hour encounter.
The two Americans had met once before on tour. At the Rome Open in May 2026, their three-set clash required nearly three hours, with Gauff saving a match point before escaping 5-7, 7-5, 6-2 after being down a set.
"I think that experience helped me for today," Gauff said after the Jovic match. "I knew to expect that she was going to be at 100 from the first point to the last."
How did Gauff control the fourth-round match against Jovic?
Gauff's tactical approach against Jovic neutralized her opponent's strengths from the opening moments. After an initial tense 11-minute exchange in which both players broke serve, Gauff seized control by taking the ball early off both wings and reeling off six consecutive games to claim the first set in just 33 minutes. According to Tennis Majors, this run of six straight games proved decisive in establishing her dominance.
The second set followed a similar pattern. When Jovic managed to break for 3-2 in the middle of the set, her momentum proved fleeting. Gauff immediately broke back and then produced what she described as her cleanest return game of the evening, racing to love-40 before Jovic sent a forehand long for 5-4. Serving for the match, Gauff rattled off four consecutive points from love-30, sealing victory when Jovic sent a backhand into the net.
What was Gauff's mental approach in the quarter-final comeback?
Gauff's ability to recover from near-defeat against Andreeva stemmed from a fundamental shift in her psychological approach to competition.
"I think I'm doing a good job of when I maybe miss opportunities or lose some games, just keeping it in the past and focusing on the present," Gauff explained. "I don't view it as opportunities lost sometimes. I try to just view it as what to do better and just trusting that I'll be in the same position again."
During the quarter-final match, Gauff drew inspiration from a moment of resilience she had witnessed the previous day. Frances Tiafoe had mounted a dramatic comeback against Alex Michelsen on the same court, saving match points to reach the men's semi-finals.
"I was watching the end of that set, and it looked like he was down and out," Gauff said. "And sometimes you just need a chance, and I think I got my chances today."
As she fought through the second-set tiebreaker, Gauff's focus narrowed to immediate survival rather than victory.
"I was just really determined to not lose that second set, because I felt like I worked so hard to give myself opportunities and lost them," she said. "One point turned into another. Honestly, once the third set started, I felt pretty confident that I was going to come out with that one."
The source of her confidence extends beyond any single stroke.
"I think that gives me confidence knowing that I have probably, up to this point, like, a plan D," Gauff said. "There's comfortability in having options. If plan A doesn't work, there's B, there's C and there's D."This versatility has become her hallmark, allowing her to adapt to different opponents and circumstances.
More fundamentally, Gauff's escape was rooted in a self-belief that has become her fallback when technical elements of her game desert her.
"Honestly, just believing is all I can do," she said. "I mean, the game may not always show up, but, you know, I can control the belief in myself. I think even if it's delusional, I think the more instances that I keep showing up and maybe being successful in those moments, maybe that delusion will be more factual, I guess."
How far has Gauff come in a year?
The contrast between Gauff's current form and her position 12 months earlier could hardly be starker. She entered last year's US Open facing questions about her trajectory before exiting in the fourth round. The subsequent partnership with MacMillan has gradually transformed her game, yielding increasingly impressive results at major tournaments and leading to her Cincinnati title victory just before arriving in New York.
Her quarter-final escape against Andreeva offered further evidence of how far her perspective has evolved.
"Sometimes you're just so focused on the now, now, now, because you want it now," Gauff said. "But in the grand scheme of things, I'm definitely sitting here with a different mindset and perspective than I was last year. If anything, it inspires me a little bit more to keep working, as I see how much I have improved in a year. So I'm like, OK, if I keep putting in the work and keep refining things, my serve has definitely gotten better. Even though my serve didn't show up well, it's OK. It will show up tomorrow. The fact that I'm also speaking like this is probably my worst service match, at 12 doubles in a three-setter, I probably would have taken that last year, like, so much."
Should Gauff win the tournament and Rybakina fail to advance in her semi-final, Gauff would reach the world No. 1 ranking for the first time in her career. Her quarter-final victory has also added to her precocious record of deep runs at the grand slams. She has now reached seven major semi-finals before turning 23, a total surpassed only by Venus Williams (13) and Serena Williams (10) among active players at that age.
Should Gauff go on to lift the trophy, she would become only the second woman in the Open era to win the US Open after saving match points—and the first since Martina Navratilova in 1986.
Who did Andreeva defeat to reach the quarter-finals?
Andreeva, the fifth-seeded Russian and reigning French Open champion, reached her first US Open quarter-final by defeating Anastasia Potapova 5-7, 6-4, 6-3 on 8 September 2026. According to Tennis Majors, Andreeva's comeback victory marked her first time advancing beyond the third round in New York. The 19-year-old came to the quarter-final in peak form, having won the French Open earlier in 2026.
Before the quarter-final, Gauff held a 5-0 head-to-head record against Andreeva. However, Gauff cautioned against reading too much into that advantage.
"Mirra is someone that I always have tough matches with," Gauff said before their quarter-final. "They've leaned my way, but I think every match could have almost gone either way. She's obviously in a different mindset now, at the top of the game coming off of a grand slam win. I think it's going to be a really athletic, tough match. Hopefully I can take my opportunities when I get them."
What awaits in the semi-finals?
Gauff's next opponent is Elena Rybakina, the second seed, according to a tournament bracket update. Gauff lost their most recent meeting in Toronto and knows exactly what awaits.
"I know I'm going to have some aces hit on me and some winners hit on me, but I'm going to keep fighting and give it my all," she said. "That's all I can do."The semi-final is scheduled for Saturday, with a place in the final at stake.
