The Russian arrived at Roland Garros on the back of winning his first clay-court title at the Italian Open but was sent crashing back down to earth with a shock defeat in Paris.

Seyboth Wild, ranked 172nd in the world, produced a sensational performance to beat Medvedev 7-6, 6-7, 2-6, 6-3, 6-4 at a shocked Court Philippe-Chatrier.

"I’ve watched Daniil play for my entire junior career and up until today," said Seyboth Wild, who last competed in a Grand Slam main draw at the 2020 US Open.

"I’ve always dreamed about playing on this court, playing these kind of players.

"In my best dreams I’ve beaten them so it’s a dream come true.

"I don’t really have words to describe what I felt when I won the match.

"It definitely was the happiest day of my life."

The other men’s singles match on Court Philippe-Chatrier saw Frenchman Gaël Monfils delight the home crowed with victory over Argentina’s Sebastian Baez.

Monfils was forced to dig deep to defeat Baez 3-6, 6-4, 7-5, 1-6, 7-5 to seal a second-round tie against Holger Rune of Denmark.

The Danish sixth seed, who reached the final of last week's Italian Open, dropped a set in his 6-4, 3-6, 7-6, 6-2 win over Christopher Eubanks of the United States.

There were no such problems for last year’s French Open finalist Caspar Ruud of Norway who won his opening-round match in straight sets.

The fourth seed saw off Swedish qualifier Elias Ymer 6-4, 6-3, 6-2 in just over two hours.

Germany’s Alexander Zverev, a two-time French Open semi-finalist, started his campaign with a 7-6, 7-6, 6-1 triumph against Lloyd Harris of South Africa.

Bulgaria’s Grigor Dimitrov, Chile’s Nicolas Jarry and American duo Taylor Fritz and Tommy Paul also won in straight sets.

Defending champion and world number one Iga Świątek of Poland started her bid for a third French Open crown with an emphatic 6-4, 6-0 thrashing of Spain’s Cristina Bucșa.

Arguably the biggest shock in the women’s singles today was Ukraine’s Lesia Tsurenko’s win over Barbora Krejčíková of the Czech Republic.

The former world number two won the title in 2021 but has been knocked out in the first round courtesy of Tsurenko’s 6-2, 6-4 success on court seven.

Canada’s Bianca Andreescu, the 2019 US Open winner, came from behind to defeat Belarusian 18th seed Victoria Azarenka 2-6, 6-3, 6-4.

Tunisia’s seventh seed Ons Jabeur swept aide Italy’s Lucia Bronzetti, while Kazakh fourth seed Elena Rybakina thumped Czech qualifier Brenda Fruhvirtova 6-4, 6-2.

American ace Coco Gauff, who is seeded sixth in Paris, survived a first-round scare as she bounced back from losing the first set to beat Spain’s Rebeka Masarova 3-6, 6-1, 6-2.

Competition is due to continue tomorrow with women’s and men’s second-round matches.
