Upsets mark French

Martina Trevisan scored a 6-4, 6- 4 victory against No. 5 seed Kiki Bertens, and Iga Swiatek defeated No. 1 seed Simona Halep 6-1, 6-2 at the French Open on Sunday. On the men’s side, U.S. Open runner-up Alexander Zverev lost 6-3, 6-3, 4-6, 6-3 to 19-year-old Jannik Sinner.

PARIS — Martina Trevisan has been doing video chats from her hotel room with her mental coach every day along the way to the quarterfinals at Roland Garros, a run the 159th-ranked qualifier acknowledges is “a little” shocking, just not as much to her as to everyone else.

So after Trevisan’s 6-4, 6-4 victory against No. 5 seed Kiki Bertens at Court Suzanne Lenglen on Sunday, which was just as out-of-nowhere at this outof-nowhere French Open as Iga Swiatek’s 6-1, 6-2 win against 2018 champion and No. 1 seed

Simona Halep over at Court Philippe Chatrier, the 26-yearold from Florence, Italy, planned to stick to the routine.

It’s helped her for the past two years, not merely the past two weeks, which also featured unexpected wins over Coco Gauff and 20th-seeded Maria Sakkari.

Trevisan’s tennis coach, Matteo Catarsi, described one of the goals of the sessions with Florida-based Lorenzo Beltrame, whose clientele also includes three- time major semifinalist

Johanna Konta, this way: “Not to feel uncomfortable in this environment, like someone who played in Grand Slam qualifying, but to feel like a queen, like a star.”

While Rafael Nadal overwhelmed qualifier Sebastian Korda 6-1, 6-1, 6-2 — the 20-yearold American, whose father won the 1998 Australian Open, was so star-struck he asked his idol for an autograph after the rout — and U.S. Open champion

Dominic Thiem held off French wild-card entry Hugo Gaston 6-4, 6-4, 5-7, 3-6, 6-3, the unpredictable outcomes kept arriving at Roland Garros in the fourth round Sunday.

U.S. Open runner-up Alexander Zverev lost 6-3, 6-3, 4-6, 6-3 to 19-year-old Jannik Sinner of Italy, then said he had a fever and was short of breath, two symptoms that raise red flags during a coronavirus pandemic that postponed the French Open from May-June to September-October.

Sinner is the first man to reach the quarterfinals in his debut in Paris since Nadal 15 years ago and now faces the 12-time champion. Thiem, runner-up to the King of Clay the past two years, plays No. 12 seed Diego Schwartzman, a 6-1, 6-3, 6-4 winner against Lorenzo Sonego.

In the other women’s matches, No. 3 Elina Svitolina beat

Caroline Garcia 6-1, 6-3 and next takes on Nadia Podoroska, a qualifier from Argentina who is ranked 131st and eliminated Barbora Krejcikova 2-6, 6-2, 6-3.
