Roland Garros 2026: Mensik Stuns Navone in Upset as Czech Advances to Third Round
PARIS — Jakub Mensik, the 27th-ranked Czech, delivered one of the biggest shocks of Roland Garros 2026 on Wednesday, defeating world No. 38 Mariano Navone in a four-set thriller (3-6, 6-3, 6-4, 6-3) to advance to the third round of the French Open. The victory marks Mensik’s deepest Grand Slam run since reaching the Australian Open quarterfinals in 2024 and hands Navone his first loss at the tournament after a dominant clay-court season.
How the Upset Unfolded: A Tactical Breakdown
The match was a masterclass in adaptability. Navone, who entered the match on a 14-match clay-court win streak, dominated the opening set with aggressive baseline rallies, breaking Mensik twice in the first game. His 6-3 victory in the first set included 37 winners and just 13 unforced errors—a testament to his current form.
But Mensik, who had struggled on clay earlier this season (4-3 record), adjusted his game plan. The Czech opened the second set with a 6-3 victory, capitalizing on Navone’s tendency to overcommit on second serves. Mensik converted 6 of 11 break points while holding all three of his own service games.
Key Statistics:
- First Serve %: Mensik (41%) vs. Navone (62%)
- Break Points Converted: Mensik (6/11) vs. Navone (4/12)
- Aces: Navone (18) vs. Mensik (12)
- Double Faults: Navone (10) vs. Mensik (4)
Navone fought back in the third set, but Mensik’s ability to mix in drop shots and slice returns disrupted the Argentine’s rhythm. The Czech’s defensive prowess—particularly his backhand—allowed him to extend rallies when Navone’s forehand was targeted.
The decisive fourth set saw Mensik close out the match with clinical precision. His ability to dictate points from the baseline, particularly on Navone’s weaker backhand side, proved decisive.
| Set | Score | Break Points | Key Moment |
|---|---|---|---|
| 1 | Navone 6-3 | Mensik 0/3 | Navone breaks early, holds all service games |
| 2 | Mensik 6-3 | Mensik 6/11 | Czech converts two break points in final game |
| 3 | Mensik 6-4 | Navone 4/12 | Navone saves three match points at 5-4 |
| 4 | Mensik 6-3 | Mensik 3/5 | Mensik closes out with three consecutive service games |
What This Means for Both Players
For Mensik: The victory is a career-defining moment. Entering Roland Garros with a 4-3 clay-court record in 2026, Mensik’s ability to outlast Navone—despite the Argentine’s superior first serve and aggressive baseline game—demonstrates his resilience. His next opponent will be a major test: either a top-20 seed or another unseeded challenger in the third round.
For Navone: The loss is a setback for a player who had been on a tear. Navone’s form had been undeniable prior to this match, including a runner-up finish in Geneva last week. However, his struggles on the serve (10 double faults) and inability to convert break points (4/12) suggest he may need to refine his game plan against tougher opponents.
Context: Navone’s Clay-Court Dominance
Navone’s rise in 2026 has been meteoric. The 25-year-old Argentine has won his first ATP title in Bucharest, reached the third round of the Italian Open, and finished as runner-up in Geneva—defeating world No. 10 Casper Ruud in the process. His head-to-head record against top-50 players stands at 8-3.
Yet, his loss to Mensik highlights a common theme for rising stars: even the most dominant players can be undone by tactical adjustments. Navone’s aggressive style, while effective against physical baseliners, can be exploited by patient counter-punchers like Mensik.
What’s Next for Mensik
Mensik’s third-round opponent will be determined by the outcomes of other second-round matches. Potential foes include:
- Pablo Carreno Busta (89th, def. Jiri Lehecka)
- Thanasi Kokkinakis (100th, def. Terence Atmane in an epic 4-hour, 18-minute match)
- An unseeded player who advances from another matchup
If Mensik continues this form, he could become the first unseeded player since 2020 to reach the fourth round at Roland Garros. His next match is scheduled for Thursday, May 28, at 14:00 CET (12:00 UTC) on Court 6.
Fan Reactions and Expert Takes
Tennis analysts and fans alike have reacted to the upset:
Mensik vs Navone was one of the best matches at Roland Garros so far. The Czech’s patience and defensive skills were on full display. This could be the start of a deep run for him. #RolandGarros

Former world No. 1 Rafael Nadal, who watched the match from the stands, praised Mensik’s performance:
“Jakub played with incredible maturity today. He didn’t try to hit winners when he was behind—he waited for Navone to make mistakes. That’s how you win on clay.”
