French Open 2026 Day Five Summary

Day five at Roland Garros delivered absolute mayhem. In one of the most stunning upsets in recent years, world number one Jannik Sinner saw his 30-match winning streak and career Grand Slam dream crumble in dramatic fashion, when he physically collapsed and lost from one lead to Juan Manuel Cerundolo.

The shocks didn’t end there. 17-year-old French wild card Moïse Kouamé continued his home run with a five-set victory, while Belgium’s Raphael Collignon pulled off a huge upset over No. 5 seed Ben Shelton.

With several top players already gone, the 2026 French Open is wide open and gives someone a huge opportunity to win a Grand Slam without Sinner or Alcaraz in the way.

We saw it happen at the 2020 US Open, and the end result was a nervous tournament where everyone played as if they had something to lose. Not the best spectacle, as there were no fans at the Stadium either, so hopefully the level in Paris stays high.

Here’s a look at the key matches from day five.

Day Four French Open 2026 Round of 64 Results

Key matches

Juan Manuel Cerundolo def. Jannik Sinner (1) 3-6 2-6 7-5 6-1 6-1

In the tournament’s biggest shock, world No. 1 Jannik Sinner suffered a stunning five-set defeat to Argentina’s Juan Manuel Cerundolo.

Sinner cruised through the first two sets and led 5-1 in the third, but suddenly hit a physical wall suffering from dizziness, low energy and cramps.

He failed to serve out the match twice and never recovered. Cerundolo stormed back to win 18 of the last 20 matches and complete one of the most dramatic upsets in recent Roland Garros history.

This ends Sinner’s 30-match winning streak and his bid for the career Grand Slam in 2026. Cerundolo advances to the third round for the first time at a major.

While there was talk that Sinner might struggle on clay for five sets, I wasn’t really sure who could really compete with him to do it physically.

The first two sets were lopsided in terms of scoring, but Cerundolo kept Sinner out there for almost 2 hours before things went pear-shaped, and he took full advantage.

Moise Kouamé def. Adolfo Daniel Vallejo 6-3 7-5 3-6 2-6 7-6(8)

17-year-old French wildcard Moïse Kouamé delivered another home fan-pleasing performance, outlasting Adolfo Daniel Vallejo in a five-setter that lasted almost five hours.

Kouamé showed incredible fighting spirit and crowd-pleasing shots, saving crucial break points in the decider to win a marathon tie-break. The teenager became the youngest player to reach the third round of a major since Rafael Nadal in 2003.

However, I don’t agree with the French media hype about him. Vallejo is hardly a feared opponent, and I would expect Tabilo to beat him soundly in the next round.

Frances Tiafoe def. Hubert Hurkacz 6-7(5) 7-6(5) 6-4 6-7(1) 6-4

Frances Tiafoe, No. 19, beat Hubert Hurkacz in a high-quality five-set battle. Tiafoe showed great resilience and variety and prevailed in a match filled with momentum swings.

While Hurkacz isn’t the scalp he once was, he’s still earning hugely, and Tiafoe isn’t exactly pulling up any trees himself, so this is a strong result for the American on clay.

Felix Auger-Aliassime def. Román Andrés Burruchaga 4-6 6-0 7-5 6-1

No. 4 seed Felix Auger-Aliassime survived an early scare, losing the first set before producing a dominant response.

He cruised through the next three sets with aggressive baseline play to reach the third round comfortably after the slow start, and his draw is smooth.

Learner Tien def. Facundo Díaz Acosta 7-5 4-6 3-6 7-6(4) 6-3

18th-seeded Learner Tien battled through a tough five-setter to advance. Fresh from his Geneva title, he showed good fighting qualities and has a very reliable game, winning the pressure moments, with only three points separating the two over the course of four hours.

Raphael Collignon def. Ben Shelton 6-4 7-5 6-4

Raphael Collignon pulled off a major upset, defeating No. 5 seed Ben Shelton in straight sets to reach the third round of Roland Garros.

The 24-year-old Belgian produced a very impressive performance, blasting 30 winners while keeping unforced errors low at just 13.

He dictated play with powerful, aggressive baseline strokes and never let Shelton find his rhythm on Court Suzanne Lenglen.

This marks Collignon’s first career top-5 win and continues the streak of major upsets at this year’s tournament

The Belgian, who arrived in strong form with a Challenger final under his belt, has had some decent results this year. Together with Blockx, the Belgians have got quite a duo, and they already surpass the highly regarded Zizou Bergs.
