No. 19 Francisco Cerundolo of Argentina stunned No. 10 Daniil Medvedev of Russia 6-0, 4-6, 7-5 at Hard Rock Stadium in Miami Gardens, adding to a remarkable string of Top 10 upsets at the 2026 Miami Open. The victory marked Cerundolo’s first career meeting with the Russian and delivered Medvedev just the second 6-0 first-set loss of his ATP career. The match lasted 2 hours and 17 minutes as Cerundolo converted 7 of 12 break point opportunities while firing 24 winners against 36 unforced errors.
“When I was 6-0 up, I didn’t expect it,” Cerundolo said. “I was playing really good, but he was missing a lot. After that, things started to change a lot, but I kept fighting and kept believing.” The Argentine broke Medvedev’s first three serves in the opening set, establishing an early dominance that would prove crucial in the final outcome. Medvedev managed to convert 4 of 8 break point chances throughout the match but struggled with 41 unforced errors compared to just 15 winners.
Cerundolo drew inspiration from No. 36 Sebastian Korda’s upset victory over No. 1 Carlos Alcaraz of Spain, which occurred in the Round of 32. “I believed, because if he did it, I also could do it,” Cerundolo said of Korda’s 6-3, 5-7, 6-4 win over the world’s top-ranked player. The American’s victory over Alcaraz provided a blueprint for lower-ranked players to challenge the tournament’s elite competitors. Korda’s triumph marked one of the most significant upsets in recent Miami Open history.
The 2026 Miami Open has witnessed an unprecedented exodus of Top 10 men’s players, with Medvedev becoming the fifth such player to exit before the Round of 16. No. 6 Alex de Minaur of Australia and No. 9 Ben Shelton of the United States both lost in the Round of 64, while No. 3 Novak Djokovic and No. 5 Lorenzo Musetti withdrew before play due to injuries. Only No. 2 Jannik Sinner of Italy, No. 4 Alexander Zverev of Germany and No. 7 Taylor Fritz of the United States remained active among the Top 10 men through the early rounds.
Simultaneously, No. 54 Terence Atmane of France defeated No. 8 Felix Auger-Aliassime of Canada 6-3, 1-6, 6-3 on the grandstand court, adding another upset to the tournament’s growing list. Atmane fired just three aces compared to Auger-Aliassime’s 11 but accumulated 26 winners against his opponent’s 15. The Frenchman converted 2 of 3 break point chances while saving 4 of the 6 break points he faced, demonstrating the tactical precision that has defined many of the tournament’s surprise results.
The women’s draw has experienced similar upheaval, with No. 3 Iga Swiatek of Poland becoming the first Top 10 woman to exit earlier than expected when she lost to No. 50 Magda Linette in the Round of 64. No. 7 Jasmine Paolini of Italy and No. 8 Elina Svitolina of Ukraine followed with Round of 32 exits, creating opportunities for lower-ranked players to advance deeper into the tournament. The pattern of upsets has fundamentally altered the tournament’s competitive landscape and championship predictions.
Cerundolo will face No. 34 Ugo Humbert of France in the Round of 16, while Atmane will meet either No. 20 Frances Tiafoe of the United States or No. 13 Jakub Mensik of Czechia. The Argentine’s victory over Medvedev represents his biggest career win and positions him for a potential breakthrough performance in one of tennis’s premier tournaments. The remaining matches in the Round of 16 are scheduled to continue throughout the week at Hard Rock Stadium.
