A wound-up Daniil Medvedev suffered a shock first-round exit at the French Open when he lost 7-6(5), 6-7(6), 2-6, 6-3, 6-4 to Brazilian qualifier Thiago SeybothWild amid gusty winds on Tuesday.

Although Seyboth Wild won two Challenger (second-tier) titles on clay this season, world No. 2 Medvedev was coming into the grand slam tournament on the back of a title in Rome, having shown tremendous progress on the slowest surface.

It counted for nothing on a windswept court Philippe Chatrier, where the Russian seemed increasingly frustrated, arguing with the umpire and the fickle Paris crowd over a line call in the fourth set.

Seyboth Wild just had too much pace and power for Medvedev, who never found his range and capitulated after four hours and 15 minutes.

“I watched Daniil play since I was junior and beating him on such a court is a dream come true,’ the world No. 172 said.

“I tried to use my forehand against his and it worked pretty well.

"I started cramping at the start of the second set but I used my mental strength to play my best tennis.”

Casper cruises

Fourth seed Casper Ruud coasted into the second round with a 6-4, 6-3, 6-2 victory over Swedish qualifier Elias Ymer to kick off his bid for a second straight final in Paris.

Ymer was no match for the baseline power of the Norwegian world No. 4 , who lost in the 2022 final to Rafael Nadal, an absentee this year.

“Last year was one of the best tournaments of my life,” Ruud said.

“You want to defend what you did last year which was incredible for me and I will try to do it again.”

He got his first break at 3-3 when Ymer sailed a forehand wide.

The Norwegian, whose season start was far from successful before winning the title on clay in Estoril in April and reaching the last four in Rome two weeks ago, broke his opponent again at the start of the second set.

Pummelling Ymer with thundering baseline winners, Ruud was in no mood to slow down, and even after the Swedish journeyman clawed his way back with a break of his own he responded with another break to bag the set.

Ymer, whose brother Mikael was eliminated in the first round as well, had no answer to Ruud’s power game.

Danish sixth seed Holger Rune overcame a mid-match wobble to see off French Open debutant Christopher Eubanks 6-4, 3-6, 7-6(2), 6-2.

Easy for top seed

World No.1 Iga Swiatek launched her title defence by easing past Spain's Cristina Bucsa 6-4, 6-0 into the second round.

She had beaten the Spaniard in under an hour, losing just one game, at this year's Australian Open but Swiatek had a less-than-perfect run-up to Paris, retiring from her Italian Open quarter final after suffering a thigh injury two weeks ago.

The 21-year-old triple Grand Slam winner was broken twice in her first three service games as a determined Bucsa, ranked 70th in the world, mixed it up and initially succeeded in throwing her opponent off balance.

But the top seed heeded that wake-up call towards the business end of the set and broke back to seal it.

The Pole snatched another break at the start of the second set with a thundering crosscourt forehand winner and never looked back.

World No. 7 Ons Jabeur made a near-flawless start to her campaign as she brushed aside unseeded Italian Lucia Bronzetti 6-4, 6-1 on Tuesday to reach the second round.

Jabeur has had a stop-start season in which she had a minor knee surgery before winning the title in Charleston and skipping the Madrid Open with a calf problem but the Tunisian was in peak form in Paris as she eased through the first set.

Bronzetti came into the clash on Court Philippe Chatrier high on confidence after winning the first singles title of her career in Rabat but the 24-year-old’s hopes of ending a five-match losing run at the majors faded as the contest wore on.

Jabeur, the runner-up at last year’s Wimbledon and US Open, blended guile and power as she reeled off the breaks in the second set to go 5-0 up before dropping serve.

The 28-year-old quickly shook off that minor dip to comfortably close out the contest in the following game when Bronzetti sent a shot wide at the net.

American sixth seed Coco Gauff recovered from an error-strewn start to begin her quest with a 3-6, 6-1, 6-2 victory over Spain’s Rebeka Masarova.
