Teenage sensation Joao Fonseca has continued what could be his breakout grand slam tournament at the French Open, reaching the quarterfinals of a major for the first time.

Having already stunned 24-time grand slam champion Novak Djokovic in the third round, Fonseca produced a dazzling display to beat two-time Roland-Garros finalist Casper Ruud and reach the last eight in Paris.

It took just under four hours on Court Philippe-Chatrier for the 19-year-old to emerge victorious, 7-5, 7-6(10/8), 5-7, 6-2 over 15th-seeded Ruud, who finished runner-up in 2022 and 2023.

Fonseca's victory came after twice rallying from two sets down in this tournament, pushing his total time on court to a gruelling 14-and-a-half hours.

"It's a first time for me, it's a new experience getting through to the second week of a grand slam."

Fonseca utilised his massive forehand and serve, but mixed in serve and volley points as Ruud forced him to pull out all his tricks.

Fonseca, who matched Ruud exactly with 51 winners and 52 unforced errors, said his play was as much instinct as intelligence.

"I just try to be me on court, try to be happy, try to hit winners, try to hit good shots, try to be entertainment," he said.

On the women's side, Iga Świątek's 25th birthday celebrations turned sour when the former ​champion lost to 15th seed Marta Kostyuk in the fourth round, and her quest for a fifth title ended just when she had looked to be rediscovering her form.

Świątek's shock 7-5, 6-1 loss came amid a chaotic spell at Roland-Garros, with Djokovic, men's world number one Jannik Sinner and defending women's champion Coco Gauff all going out in the previous three days.

It leaves world number one Aryna Sabalenka as the favourite to lift her first title ​in Paris, though Ukrainian Kostyuk will be one to watch as ‌she builds on the momentum that has helped her sparkle on clay this season.

"I'm still in shock," Kostyuk said in an on-court interview after reaching her first French Open quarterfinal.

"I feel like I've given myself more space to just create something, to challenge my opponents. I woke up in the morning, and all I thought was, '
