Day 9 at Roland-Garros 2026 completed a quarter-final lineup as unpredictable as it is compelling. Between a Brazilian prodigy’s confirmation and unexpected breakthroughs on the women’s side, this edition continues to defy expectations.

João Fonseca delivered the men’s performance of the day by defeating Casper Ruud 7-5, 7-6(8), 5-7, 6-2 in three hours and fifty-five minutes on Philippe-Chatrier. The 19-year-old Brazilian, who had already eliminated Novak Djokovic in the previous round, reaches his first Grand Slam quarter-final. The second set crystallised all the tension: a tiebreak that stretched to 10-8 where a controversial umpire decision shifted the momentum. Television replays showed Hawk-Eye placing the ball out at 8-8, where the chair umpire had awarded the point to Fonseca. Ruud, a two-time finalist in Paris, will harbour regrets. Fonseca, meanwhile, became the first Brazilian man to reach the Roland-Garros quarter-finals since Gustavo Kuerten.

Felix Auger-Aliassime gave Alejandro Tabilo no chance. The 16th seed cruised 6-3, 7-5, 6-1 to reach his maiden Roland-Garros quarter-final. "I feel at home here," he said after the win. He will face world No. 10 Flavio Cobolli, who needed four sets to overcome American qualifier Zachary Svajda 6-2, 6-3, 6-7(3), 7-6(5) in three hours and nineteen minutes.

On the women’s side, Diana Shnaider produced the upset of the day by overpowering Madison Keys 6-3, 3-6, 6-0 in one hour and forty-six minutes. The 21-year-old Russian reaches her first Grand Slam quarter-final and will face the winner of the blockbuster between and Naomi Osaka. The decisive third set, a ruthless 6-0, showcased Shnaider’s ability to raise her level when it matters most.

Maja Chwalinska’s fairy tale continues. The Polish qualifier, ranked 114th, dispatched Diane Parry 6-3, 6-2 in one hour and thirty-three minutes in front of a torn Parisian crowd. Chwalinska will face Anna Kalinskaya in the last eight. Mirra Andreeva, the eighth seed, confirmed her status by defeating Jil Teichmann 6-3, 6-2 to reach her third consecutive Roland-Garros quarter-final. She will meet 36-year-old Sorana Cirstea in a clash of generations.

The quarter-final draw is now complete, and it tells a story: a Roland-Garros without a clear ruler, where the next generation has seized power.
