Argentina's Francisco Cerundolo delivered one of 2026's most dramatic tennis upsets on Monday, overcoming former World No. 1 Daniil Medvedev 6-0, 4-6, 7-5 at the Miami Open. The 27-year-old's victory marks his first Top-10 win this season and extends his impressive record at the Florida tournament.
Medvedev entered the match fresh from defeating Carlos Alcaraz at Indian Wells, but found himself outmaneuvered by Cerundolo's aggressive baseline play. The South American dominated early, securing the first set in just 29 minutes before the Russian mounted a characteristic comeback.
"I didn't expect to be up 6-0 in the first set," Cerundolo admitted post-match. "Daniil's had an incredible year with two titles already. When he fought back, I just focused on trusting my forehand and movement."
The deciding set saw both athletes push through Miami's humid conditions, with Cerundolo ultimately clinching victory through a combination of powerful groundstrokes and tactical net approaches. The result ends Medvedev's quest for a Tour-leading 20th win this season.
This victory positions Cerundolo as a dark horse contender in the tournament, while raising questions about Medvedev's ability to maintain peak performance through the grueling ATP calendar. Tennis analysts suggest the match could signal a shift in hardcourt dynamics as younger players challenge established champions.
