PARIS — After letting another big lead slip with an error-strewn performance at the French Open, top-ranked Aryna Sabalenka felt like getting as far away from the courts as possible.

“Just want to quit tennis right now,” Sabalenka said after wasting a lead of a set and two breaks in a 3-6, 7-5, 6-0 loss to Diana Shnaider in the quarterfinals on Wednesday. “We’ll see in few days. Hopefully I’ll get back on track mentally.”

Sabalenka’s wait for a first French Open title continues despite the four-time major winner leading 4-1 in the second set and being two points from victory while serving for the match at 5-4. What followed was a complete collapse as she lost 12 of the last 13 games against a player appearing in her first Grand Slam quarterfinal, looking increasingly frustrated and forlorn in the windy conditions.

Just like her loss to Coco Gauff in last year’s final, when she also won the first set before becoming undone with a slew of unforced errors, this one will take some time to get over.

“You know those rooms where you just go in and you smash everything,” Sabalenka said. “Probably I will spend a whole day tomorrow over there destroying stuff. Maybe it will help, maybe not.”

Shnaider next faces Maja Chwalinska, who extended her remarkable Roland Garros run by beating No. 22-seeded Anna Kalinskaya 7-6 (7-3), 6-3.

Italian finalist

In the men’s quarterfinals, 10th-seeded Flavio Cobolli beat No. 4 Felix Auger-Aliassime 4-6, 6-4, 6-4, 6-4 and will face fellow Italian Matteo Arnaldi for a spot in the final.

Arnaldi advanced when Matteo Berrettini, yet another Italian, retired due to an apparent physical issue with Arnaldi leading 7-5, 5-2.

Berrettini appeared to have his left groin area treated during a medical timeout earlier in the second set.

The strong Italian showing comes despite top-ranked Jannik Sinner getting stunned in the second round.

Second-seeded Alexander Zverev and No. 26 Jakub Mensik will meet in the other semifinal.

Another upset

Sabalenka’s loss was just the latest big upset in a tournament where defending champion Gauff (third round) and four-time winner Iga Swiatek (fourth round) already tumbled out.

Jannik Sinner, last year’s runner-up, served for the match in a second-round defeat, and 24-time major winner Novak Djokovic wasted a two-set lead in a third-round loss.

That opened things up for lesser-known players. According to Opta, this is the first major without a former champion in either the men’s and women’s semifinals since the French Open in 1977.

From qualifier to contender

The unseeded Chwalinska came through three qualifying rounds to become only the second Polish woman to reach the semifinals at Roland Garros, along with Swiatek.

Chwalinska said British player Emma Raducanu’s run to the 2021 U.S. Open title as an 18-year-old qualifier had inspired her.

“It was such an impressive run, you know,” Chwalinska recalled. “Also, she was so young.”
