Aryna Sabalenka's pursuit of a first French Open title ended abruptly on Wednesday as she was defeated in the quarterfinals by Russian 25th seed Diana Shnaider. The world number one squandered a significant lead, losing 3-6, 7-5, 6-0 on Court Philippe-Chatrier in Paris under challenging windy conditions.

Sabalenka, a four-time Grand Slam champion, appeared poised for victory after taking the first set and establishing a double-break advantage early in the second. She led 5-4 while serving for the match and was two points away from clinching the win. However, a string of unforced errors and growing frustration allowed Shnaider, playing in her first major quarterfinal, to rally and dominate the remainder of the match, winning 12 of the last 13 games. Sabalenka committed a total of 57 unforced errors, a figure that underscored her unexpected collapse.

“I just want to quit tennis right now,” Sabalenka said after the match, reflecting on her disappointment. She admitted to struggling mentally and emotionally, likening her frustration to last year’s French Open final loss against Coco Gauff, where she also gave up a strong lead. Sabalenka described her mindset during the loss as overthinking leading to simple mistakes and missed opportunities. The windy conditions, combined with the tournament's decision to keep the roof open on the main court, added to the difficult playing environment for several competitors, including Sabalenka and others such as Anna Kalinskaya.

Shnaider, 22, expressed her elation after the upset and praised her focus on battling point by point rather than the scoreboard. “I’m super happy. It’s been a special tournament for me,” she said, acknowledging the challenge of facing a top-ranked opponent for the first time. Shnaider now advances to the semifinals to face Polish qualifier Maja Chwalinska, who extended her breakthrough run by defeating 22nd-seeded Anna Kalinskaya 7-6(3), 6-3. Chwalinska, ranked outside the top 100, has emerged as one of the surprise contenders of the tournament, drawing inspiration from previous qualifier successes in major events.

Sabalenka's loss marks another major upset in a tournament that has seen several top seeds eliminated early, including defending women’s champion Coco Gauff in the third round and four-time winner Iga Swiatek in the fourth. Notably, this French Open is the first Grand Slam since 1977 to feature no former champions in either the men's or women's semifinals, reflecting the open and unpredictable nature of the competition this year.

In the men’s quarterfinals, 10th-seeded Flavio Cobolli upset No. 4 Felix Auger-Aliassime, setting up an all-Italian semifinal clash against Matteo Arnaldi, who advanced after Matteo Berrettini retired with a left hip injury. The tournament continues to reveal new talents and unexpected storylines as it progresses toward the final weekend.
