pressure reshapes – Day 9 at Roland Garros turned the spotlight on what happens when tennis pressure finally catches up. Maja Chwalińska, a qualifier ranked world No. 114, surged into her first Grand Slam quarterfinal. Anna Kalinskaya and Anastasia Potapova traded nerves and mome
On Court Philippe-Chatrier, Maja Chwalińska didn’t just beat Diane Parry. She made the idea of “impossible” feel like something you could outplay.
The 24-year-old Polish qualifier smiled Monday when asked about the moment—her own moment—after she defeated Parry. “Well, it’s definitely a big surprise for me, and I didn’t expect it, surely,” she said.
Chwalińska’s run is already rewriting what the tournament looks like from the outside. The world No. 114 is through three qualifying rounds. has dropped just one set. and it’s carried her all the way to her first career Grand Slam quarterfinal. The win over Parry came after earlier victories that kept stacking up: she took down Olympic champion Zheng Qinwen in the first round. then upset No. 23 seed Elise Mertens in the second. She also beat 2021 semifinalist Maria Sakkari in the third round before closing out Parry, 6-3, 6-2 in the fourth.
Her quarterfinal place matters in a very specific way for Roland Garros history. Chwalińska is the first qualifier to reach the women’s singles quarterfinals at Roland Garros since Martina Trevisán in 2020.
Even the small details of the day carried a kind of pressure-proof calm. On Court Philippe-Chatrier, after the points were finished, she took a picture of the plaque for Rafael Nadal that adorns the court.
When she spoke afterward, it wasn’t just about the match. She sounded grateful for the stage and for the crowd. “I’m really grateful for this opportunity,” Chwalińska said. “It’s such a beautiful court.”
She added that she knew what was coming. with the French crowd involved and a match against Parry that would demand patience. “I knew coming in that it’s going to be a very tough match. you know. with the French crowd. as well. but they were very respectful. I think. They supported Diane, but me as well. I was very grateful for that.”.
What makes the pressure story sharper is how quickly her dream has met the practical world. Chwalińska took a mental health sabbatical from the sport in 2021 to manage a period of depression. And this week. as a player outside the top 100. she had to handle the logistical realities of an unexpected run in an expensive city.
After her second-round match, she said in her on-court interview that she was struggling to pay for a hotel in Paris. She explained that players don’t get paid—she would make just under $550,000 for reaching the quarterfinals—until after the tournament.
Later, she said the Polish company Oshee, which sponsors her compatriot and friend Iga Świątek, stepped up to help her with accommodations. Chwalińska is hoping to extend her reservation at least a few more nights. Next, she will face No. 22 seed Anna Kalinskaya.
If Chwalińska’s quarterfinal arrives through composure under sudden spotlight, Monday’s other fourth-round matches showed how pressure behaves when it’s the one in control.
Kalinskaya and Anastasia Potapova delivered a seesawing thriller that felt like both players were searching for the “right” version of themselves—tight when leading, looser when chasing—right up until the finish line refused to give anyone comfort.
Potapova, the No. 28 seed, started well and raced to a 4-1 lead in the first set. Then she lost five straight games to let Kalinskaya take it 6-4.
In the second set, Potapova won straightforwardly. Then they moved into a decider. In the third set, Potapova went up a break three times, only to give each one straight back. That included twice when serving for the match.
Even when Kalinskaya looked steady—leading 4-1—she still ended up tight, giving up four straight games. Once into the tiebreak, it almost seemed as though the player who got ahead would be the one punished. Potapova led 3-0 and 4-2, then faltered again with the finish line in sight.
Potapova later tried to put the emotions into words. “It was a very mental match for both,” she said in a news conference afterward. “Obviously. it seems like for both of us it’s easier to play when you’re loose. because you kind of relax your body. and you just kind of let it go. and you don’t think about it.”.
Kalinskaya has been wrestling with pressure long before Monday. She has never won a WTA title, and in the Berlin Ladies Open final two years ago she missed five championship points before losing to Jessica Pegula.
After beating Potapova on Monday, she joked during her on-court interview that she had tried staying cool in the clutch moments. It didn’t last. “I was definitely nervous,” she said in a news conference.
She described the specific swing in her own match: “The match was very physical. I felt like in third set I was up in the score 4-1. Then I saw she was a bit tired. At 4-1, I started to run out of energy to finish the match, and she was coming back, so that’s why the score was up and down a lot.”
Pressure, it turns out, doesn’t just arrive—it drains you, then comes back louder.
Later, Matteo Arnaldi and Frances Tiafoe turned that same theme into a long, brutal kind of belief. By the time the match ended at Court Suzanne-Lenglen, Arnaldi was standing at the microphone in disbelief, because the story had felt like it was slipping away for hours.
More than five hours after they started, Tiafoe and Arnaldi were still fighting when the scoreboard finally agreed on something: Arnaldi won 7-6(5), 6-7(5), 3-6, 7-6(3), 6-4, in the best five hours and 26 minutes of his life.
The opening chapters didn’t look promising for the Italian. For more than two hours, it looked like Tiafoe wouldn’t offer much resistance, even after their match became knotted at 1-1.
Still, once Tiafoe was leading 4-1 in the fourth set, it looked as if he might reach a Roland Garros quarterfinal with the kind of control that feels almost inevitable. Then Arnaldi changed the tempo of the entire match.
He started scrambling all over the court, making miracle saves, darting winners down the line. He hoisted lobs that landed on the baseline and sideline. He dug out drop shots deep to the back of the court and hammered backhands down the line. With that surge, Tiafoe got tight, played with his food a little too much, and gave Arnaldi openings.
The turning point came at the exact moment where the match should have ended. Serving for the match at 5-4 in the fourth, Tiafoe went up 30-0. Then he lost five of the next six points, letting Arnaldi burst back to even.
The tiebreak started and ended with a double fault, and then they went to a fifth set.
In the fifth set, Tiafoe was on his heels from the start. Arnaldi got to 4-2. Tiafoe broke back and blasted his way to 4-4. But in the very next game, the momentum turned to mud. Tiafoe was down 0-30 after slipping and getting caked with clay. There was no escape after that—Arnaldi broke him at love.
Tiafoe then slammed his racket on his bag over and over. The result was Arnaldi at the microphone, declaring his win.
Alongside Chwalińska, Kalinskaya, and Arnaldi, other Day 9 performances kept the theme of tennis under pressure from becoming one-note.
Matteo Berrettini, for example, reached the French Open quarterfinals with a straight-sets win over Juan Manuel Cerúndolo. The win was his first appearance in the last eight of a major since the 2022 Australian Open. He came into the French Open ranked No. 107 and wasn’t expected to make noise; now he is in the last eight.
Berrettini’s road there has been shaped by injury and setbacks that kept denying him the prime years he’s earned the reputation for. He reached a career-high ranking of No. 6 five months earlier. In 2022, he required surgery for ankle and wrist injuries, and he has since been plagued by stomach and abdominal issues.
He also tested positive for COVID-19 and withdrew on the morning of his first-round match a year later, a sign of what’s come to define his timeline.
This Monday’s match came after he needed five hours and 16 minutes to beat Francisco Comesaña in the previous round. and the longer grind still didn’t make the quarterfinal place feel routine. Cerúndolo. the opponent he beat on straight sets. had played an even longer third-round match—five hours and 57 minutes—against Martín Landaluce of Spain.
After a 6-3, 7-6(2), 7-6(6) win, Berrettini said in his on-court interview that tennis was “the love of my life.” He also said, “There were moments when it was really tough to go back and hit the ball because I wasn’t ready,” and he added that he’s looked ready in Paris.
Next up for Berrettini is a quarterfinal against his compatriot Arnaldi.
Other notable results on Day 9 kept the draw shifting.
Aryna Sabalenka (1) outplayed Naomi Osaka (16) for a 7-5, 6-3 win during the first night session to feature a women’s match since 2023.
Flavio Cobolli (10) shrugged off his first dropped set of the tournament to defeat Zachary Svajda of the U.S. 6-2, 6-3, 6-7(3), 7-6(5). The Italian is into his second Grand Slam quarterfinal.
Diana Shnaider (25) delivered Australian Open champion Madison Keys (19) a final-set bagel. The Russian moved into her first Grand Slam quarterfinal with a 6-3, 3-6, 6-0 win.
Félix Auger-Aliassime (4) completed the set of major quarterfinals. The Canadian defeated Alejandro Tabilo of Chile 6-3, 7-5, 6-1.
There were also moments that traveled beyond the scoreboard. Serena Williams is coming back to tennis. The 23-time Grand Slam champion will start with a doubles wild card into Queen’s, the Wimbledon warmup event in London.
Paraguayan player Adolfo Daniel Vallejo was fined $65,000 for saying that a female umpire wasn’t strong enough to officiate his second-round match. He lost that match.
Naomi Osaka and Aryna Sabalenka’s fourth-round duel was all about star power. Rafael Jódar, who meets tournament favorite Alexander Zverev in the quarterfinals, is upending the way tennis thinks about Spanish players on clay.
And the relationship between electronic line calling and line judges on clay continues to confuse players and fans—partly because broadcasters don’t know how to explain it.
Quarterfinals are next.
