Carlos Alcaraz defeats Joao Fonseca in Miami Open second-round debut, advancing to face Sebastian Korda next
Alcaraz wins first official meeting with Fonseca at the Miami Open
MIAMI GARDENS, Fla. — Carlos Alcaraz moved into the third round of the Miami Open on Saturday, March 21, 2026, defeating Brazilian teenager Joao Fonseca 6-4, 6-4 in their first official ATP Tour meeting. The result set up a third-round matchup with American Sebastian Korda.
Alcaraz, the tournament’s top seed and a former Miami champion, controlled key moments in both sets to close out the match in straight sets. Fonseca, 19, entered the contest as one of the event’s most-followed young players after drawing significant attention during his 2025 Miami run, and he again played in front of a crowd that included a prominent Brazilian contingent.
Match context: a highly anticipated pairing after a prior exhibition
Saturday’s match was widely anticipated as an early benchmark between an established leader of the men’s game and one of its newest headline prospects. While Alcaraz and Fonseca previously shared a court in an exhibition event in Miami in December 2025, the Miami Open encounter represented their first official meeting with ATP ranking points at stake.
The pairing also carried local interest beyond the tournament grounds, following Alcaraz’s high-profile presence in Miami during the week.
What the result means for the Miami draw
With the win, Alcaraz advanced to face Korda, a U.S. player who entered Miami in form after capturing the Delray Beach title earlier in the 2026 season. Korda reached the third round by defeating Camilo Ugo Carabelli in straight sets (6-0, 6-3), setting up a meeting between one of the event’s top seeds and one of the home crowd’s leading hopes.
The Miami Open is being played at Hard Rock Stadium, with the tournament’s main ATP Masters 1000 event running in March 2026. The Alcaraz-Fonseca matchup added early-round spotlight to a field that includes multiple recent major and Masters contenders.
