French Open 2026 Day 5 Recap: Sinner Stunned in Dramatic Collapse as Chaos Reigns at Roland Garros

Day 5 of the 2026 French Open will be remembered as one of the most dramatic days in recent Grand Slam history. Under another sweltering Parisian afternoon, a stunning upset there was a stunning upset that sent shockwaves through the tournament, while a young French prospect provided a memorable home story amid the drama.

The headline act on Court Philippe-Chatrier delivered the unthinkable. World No.1 Jannik Sinner suffered a dramatic collapse against Argentina’s Juan Manuel Cerundolo, losing 3-6, 2-6, 7-5, 6-1, 6-1. The Italian had raced to a commanding lead and stood one game away from victory at 5-1 in the third set. However, he suddenly hit a wall, suffering from dizziness and low energy. Cerundolo seized the moment, winning 18 consecutive points at one stage and dominating the final two sets.

“I struggled, starting to feel very dizzy. Very low on energy,” Sinner told the press afterward. “I woke up this morning, I didn’t feel very well and tried to keep the points short… I feel like it was quite OK to play. Really it was nothing against the heat, nothing against the weather.” The loss ends Sinner’s 30-match winning streak and his bid for a Career Grand Slam this year.

Next door on Court Suzanne-Lenglen, 17-year-old French wild card Moïse Kouamé delivered another thrilling performance for the home crowd. After building a two-set lead against Paraguay’s Adolfo Daniel Vallejo, Kouamé dropped the next two sets but staged a remarkable recovery to win 6-3, 7-5, 3-6, 2-6, 7-6(8) in nearly five hours. The teenager saved crucial break points in the deciding tiebreak, becoming the youngest man to reach the third round of a major since Rafael Nadal in 2003.

In the women’s draw, top seed Aryna Sabalenka overcame a tricky first set to defeat Frenchwoman Elsa Jacquemot 7-5, 6-2. Defending champion Coco Gauff also advanced comfortably, beating Egyptian qualifier Mayar Sherif 6-3, 6-2. “It was a physical tough match. I was really tested today,” Gauff said. “The scoreline doesn’t show how physical it was but obviously Mayar is a tough player. I will be focusing on getting more my rhythm back because I did not have it today.”

Other top seeds to get through to the third round included Naomi Osaka, Amanda Anisimova, Victoria Mboko, Iva Jovic, and Madison Keys.

One of the other major upsets of the day saw Belgium’s Raphael Collignon defeat fifth seed Ben Shelton 6-4, 7-5, 6-4 in straight sets. The 24-year-old produced a composed and powerful display. “I knew I had to try to stay focused on my return… and that I really had to concentrate on my own service game – that was the key,” Collignon explained.

Frances Tiafoe (19) survived a marathon five-set battle against Hubert Hurkacz, prevailing 6-7(5), 7-6(5), 6-4, 6-7(1), 6-4 after four hours and 43 minutes. Matteo Berrettini looked sharp in straight-sets victory over Arthur Rinderknech. On the other side of the men’s draw, Felix Auger-Aliassime got through in four sets, while young Americans, Brandon Nakashima and Learner Tien both advanced after tough five-set tests. Others to progress included the other Cerundolo (Francisco), Flavio Cobolli, and Matteo Arnaldi.

The heat once again played a starring role. Players battled dehydration, dizziness, and fatigue, with medical timeouts more frequent than usual. The conditions turned what should have been routine matches into tests of endurance, rewarding those who could manage their energy best over long rallies on the clay surface.

Day 5 has certainly left the 2026 French Open feeling remarkably open on the men’s side. With Sinner’s exit, the men’s draw has lost its clearest favorite, creating opportunities for players like Auger-Aliassime, Tiafoe, Berrettini, and the rising talents of Jodar and Fonseca. On the women’s side, Sabalenka and Gauff remain the leading figures, but the depth of the women’s field ensures no easy path forward.

With the heat forecast to persist for another two days, mental toughness and smart recovery will be just as important as shot-making and tactics in the days ahead.
