For the athletically blessed Jones, whose mother Loretta Harrop was a silver medallist triathlete at the Athens 2004 Olympics, it was the ultimate learning experience in her first Paris venture since reaching the girls’ singles semifinals last year.

Swiatek was less than two months older when she made her Paris debut and reached the fourth round in just her second major appearance.

Next time round, in 2020, she famously mounted the most unlikely charge for her maiden Grand Slam trophy.

“I feel like in 2019 I already played junior tournament, so I already kind of knew the vibe of the whole event, but obviously it's different playing at a pro level,” Swiatek said.

“I was just trying to do the best result possible with the game that I had, but next year, you know, maybe the difference was that every match I felt like I'm playing better and better, and I really felt like my game is fitting these courts.

“Match by match, I thought maybe I can go one more. I had many more belief, you know.”

In a tussle between the former world No.1 and former junior No.1 on Monday – they concurrently held top spot in their respective rankings in late 2024 – the third seed and four-time champion was relentless throughout, relishing the extra zing in her shots in the heat.

Swiatek could empathise with having salvaged just one game against third seed and reigning champion Simona Halep in that last-16 showing on debut.

“In 2019 I also played quite good. I remember I was a bit injured, but then with Simona, obviously she beat me pretty hard,” Swiatek said. “It was heartbreaking, but it was a lesson that I had to learn. She was playing her best game back then. For sure, without that loss, I wouldn't play much better next year, you know. That's the story.”

The novelty of being an unknown quantity worked in the young Pole’s favour particularly in her early years on tour.

While a handful of women before her had deployed such heavy-kicking and aggressive topspin, Swiatek took it to another level.

It required a period of adaptation for the rest of the field and while her rivals knew better now what to expect, execution was another matter.

“For sure players got used to it. I remember it was all a surprise in 2022 [her most dominant season],” she said.

“It was quite interesting that next year I felt totally different. I think this is what people say when they say it's harder to stay on the top, because you need to adjust your game so it's not that simple for people anymore. Yeah, they get used to it, for sure.

“But on the other hand, I can still make these shots better and they still work. When I played against Ash [Barty], I knew exactly what she's gonna play, but she did it so good that I was still losing these points.

“I knew exactly that she's gonna slice me to the backhand. I'm gonna try to, you know, pick it up with my backhand topspin and she's gonna finish me with her forehand.

"But still I played this one not so good, you know, because her slice was amazing. She played her forehand so well, that I still had no chance.”

Swiatek preserved her flawless Grand Slam record in main draws and qualifying against players outside the top 100 to set a second-round meeting with Czech Sara Bejlek.

For Jones, there was much to take away from her first outing on Chatrier. As Swiatek can vouch, it’s how you respond next time round that matters.
