She has never particularly liked playing on the clay, either, having not progressed past the third round in Paris, and is now ranked 134th in the world.

Swiatek, by contrast, has looked invincible on her best surface this season, winning her last 13 matches including titles in Madrid and Rome, and was a red-hot favourite for a third successive Roland Garros title, and a fourth in five years.

Osaka’s start was not very encouraging but, broken in the first game, she settled as the opening set wore on and hit back for 4-4 and forced a set point on Swiatek’s serve.

Swiatek averted that crisis and, when she took a one-sided tie-break, the game looked up for Osaka.

But the 2021 US Open champion began swinging and Swiatek started scrambling.

Such has been Swiatek’s dominance at the tournament she had only previously dropped seven sets in five years at Roland Garros.

But at times she looked on in bewilderment as Osaka pummelled winner after winner – she hit 54 in all – past her to level the match.

In the decider Osaka hit an astonishing five winners in one game, even standing and admiring the backhand which fizzed across Swiatek to clinch another break.

Osaka had a match point on her racket but Swiatek repelled it with a fine return and instead a forehand into an open court that floated millimetres too long allowed the 22-year-old from Poland to break back.

The pressure was telling on both players, with Swiatek berating a spectator for calling out during a point.

Yet, when Osaka tightened up badly and double-faulted Swiatek, who had trailed 5-2, served for the match and an enthralling contest of immense quality ended when the Osaka’s backhand drifted wide.

Swiatek had not forgotten the scream from the crowd which cost her a point afterwards and told them: “I am sorry to bring this up. I have huge respect for you guys and I know we are playing for you. This is entertainment.

“But sometimes under a lot of pressure when you scream something during the rally or right before the return, it’s really, really hard to be focused.”

Osaka was reduced to tears afterwards but was encouraged by the progress she had made and even issued her rival a friendly challenge on the American hardcourt swing and US Open, which she won in 2018 and 2020.

She said: “I cried when I got off the court, then I thought that I watched Iga win this tournament last year when I was pregnant.

“When I think about it like that I think I’m not doing too badly. I would love to play her on my surface and see what happens.

“I also said in Australia that I’m setting myself up for September anyway.”

“I think they were both nervous, understandably so. Naomi’s game style is to go for her shots no matter what so when her arms started to feel a little bit tighter, that made all the difference,” said Laura Robson on Eurosport.

“You can see she was trying to commit to the same forehands but it wasn’t quite as free with that and her footwork.

“She handled it pretty well but what a showcase for women’s tennis!”

Tunisia’s Ons Jabeur beat Colombia’s Camila Osorio 6-3 1-6 6-3 in a roller-coaster match to move into the third round.

Jabeur hardly put a foot wrong in the opening set, combining power and finesse to put Osorio on the backfoot but a fall in the second set upset her rhythm.

That opened the door for Osorio to claw her way back into the contest while Jabeur made several unforced errors as the Colombian took a set off the eighth seed for the first time in three meetings.

Both players struggled on serve in the decider which had five break points converted, but it was Jabeur who raised her intensity towards the end, taking a 4-1 lead before wrapping up the match with 31 winners.

Former Australian Open Champion and French Open finalist Sofia Kenin breezed into the third round with a convincing 6-3 6-3 victory over home hope Caroline Garcia.

“Yes, I am super happy it means a lot that I won today, Garcia is an amazing player. I am sorry for winning,” the American said. “I am putting in the hard work and it’s paying off, merci.”
