The Miami Open finally found its rhythm on Thursday after rain wiped out Wednesday’s schedule, forcing tournament organizers into a packed day that mixed late finishes, early surprises and some of the most compelling storylines of the week.
With the backlog pushing big names, rising prospects and veterans onto a crowded order of play, March 19 felt like the first true surge of the tournament.
The men’s draw produced one of the day’s biggest crowd moments when Brazil’s João Fonseca fought past Fabian Marozsan 6-4, 3-6, 6-2. The 19-year-old handled the pressure of a lively stadium atmosphere and moved into a second-round showdown with world No. 1 Carlos Alcaraz, giving the event one of its first marquee matchups of the week.
Fonseca’s win also reinforced the sense that Miami has become one of the best stages for the sport’s next wave, especially for players who can draw strong support from South Florida’s international crowd.
Fonseca was not the only young name to break through. France’s Moise Kouame, just 17, defeated Zachary Svajda in three sets, while Spain’s Rafael Jodar and Martin Landaluce also advanced. Thursday’s results gave the ATP side a distinctly transitional feel, with teenage and early-20s players pushing their way into the spotlight alongside established names still trying to steady their seasons.
There were also notable early exits and warning signs for some better-known players. Former finalist Grigor Dimitrov was knocked out by Raphael Collignon in a tight three-setter, while Hubert Hurkacz fell in straight sets to Ethan Quinn. Denis Shapovalov also exited in the opening round, losing to Botic van de Zandschulp.
For a tournament that often rewards experience on hard courts, Thursday showed how quickly that script can flip when the schedule is compressed and conditions get uneasy after weather disruptions.
The men’s draw still had its share of steadier hands. Stefanos Tsitsipas advanced in straight sets, Roberto Bautista Agut came through two tiebreaks, and Alejandro Tabilo, Mariano Navone and Camilo Ugo Carabelli all moved on in a strong day for Latin American and South American players. Reilly Opelka also survived a three-set battle with Nuno Borges, another sign that opening-round matches in Miami were offering very little margin.
On the women’s side, the most striking result came late, when Magda Linette rallied from a set down to beat second seed Iga Swiatek 1-6, 7-5, 6-3. According to the WTA, the win ended Swiatek’s 73-match opening-round winning streak and gave the tournament its first major upset.
In a draw that still features several top contenders, it was the sort of result that immediately changes the shape of the section and opens the door for a deeper surprise run.
Alexandra Eala added another memorable chapter to her Miami story by outlasting Laura Siegemund in three sets in the longest match of her career. The WTA said the match lasted more than three hours, and it fit the tone of the day perfectly: physical, delayed, uneven at times, but rich in tension.
Francesca Jones also produced a headline result by beating Venus Williams in straight sets, while Camila Osorio moved past Katerina Siniakova to give the women’s draw another notable performance from a Latin American player.
What stood out most on Thursday was not a single result but the mood of the event. After a weather-hit start, the Miami Open suddenly felt crowded with storylines. The Alcaraz-Fonseca matchup now gives the men’s draw a must-watch second-round clash. Swiatek’s early exit has shifted the women’s field.
Eala’s resilience keeps one of the tournament’s most intriguing rising players alive. And across both tours, a day that began as a scheduling headache ended up supplying exactly what the tournament needed: noise, unpredictability and momentum.
