Sebastian Korda Stuns World No. 1 Carlos Alcaraz 6-3, 5-7, 6-4 at Miami Open

World No. 36 Sebastian Korda eliminated top-seeded Carlos Alcaraz in a 2-hour, 19-minute battle to reach the fourth round in Miami Gardens.

Sebastian Korda secured a 6-3, 5-7, 6-4 victory over world No. 1 Carlos Alcaraz on Sunday afternoon in the third round of the Miami Open. The contest lasted exactly 2 hours and 19 minutes on the hard courts of Miami Gardens, Florida. Korda, currently ranked No. 36 in the ATP standings, became the lowest-ranked competitor to topple the Spaniard since David Goffin achieved a similar feat as world No. 55 during the second round of this event in the previous season. Alcaraz entered the stadium with a 17-2 match record for the current calendar year, having recently reached the semifinals at Indian Wells before falling to Daniil Medvedev.

The statistical breakdown of the opening set favored the American, who broke Alcaraz's serve twice to claim a 6-3 lead. Momentum appeared to shift decisively when Korda served for the match at 5-4 in the second set, only for the 22-year-old top seed to ignite a comeback. Alcaraz reeled off five consecutive games, snatching the second set 7-5 and forcing a third-set decider. Despite the surge from the reigning Australian Open champion, Korda maintained composure in the final frame to break serve and hold his own, ultimately closing out the match on his first opportunity in the tenth game of the third set.

Korda’s advancement marks his first career win over a world No. 1, a milestone achieved by committing to aggressive baseline play during high-pressure rallies. Alcaraz admitted following the loss that while the scoreline remained close throughout the afternoon, his opponent consistently found better solutions during the deuce points and break-point opportunities. The victory propels the Florida native into a fourth-round encounter where he will face either the 14th-seeded Karen Khachanov or the teenage qualifier Martin Landaluce. This exit represents a significant blow to the men's draw, as the tournament's highest-ranked player departs before the round of 16.

American success extended beyond Korda’s upset on Sunday. Taylor Fritz, the sixth seed, moved into the next phase of the competition with a disciplined 6-3, 6-4 win over fellow countryman Reilly Opelka. Fritz relied on a high first-serve percentage to neutralize Opelka’s powerful delivery, never facing a break point during the 84-minute match. Meanwhile, 22nd-seeded Tommy Paul survived a grueling three-set marathon against Raphael Collignon. Paul took the first set 6-2, dropped the second 3-6, and eventually secured the win in a third-set tiebreak, 7-6 (5), after nearly three hours on court.

In other men's singles action, No. 21 Jiri Lehecka and No. 29 Tomas Martin Etcheverry both validated their seedings by winning their respective third-round matches. Lehecka utilized 12 aces to navigate his path forward, while Etcheverry relied on consistent baseline depth to frustrate his opponent. These results ensure a diverse field for the upcoming fourth-round matches, though the absence of Alcaraz leaves a power vacuum in the top half of the bracket. The Spaniard will now turn his attention to the upcoming clay-court season following this unexpected hard-court setback.

The women’s draw experienced its own share of volatility on Sunday, with four seeded players eliminated in a single afternoon. No. 7 Jasmine Paolini fell to the 25th-seeded Jelena Ostapenko in a three-set battle that showcased Ostapenko’s trademark high-risk power hitting. Elina Svitolina, the ninth seed, was ousted in straight sets by Hailey Baptiste, who recorded one of the biggest wins of her career. Additionally, No. 11 Ekaterina Alexandrova and No. 18 Iva Jovic were sent home, further thinning the ranks of the pre-tournament favorites as the event enters its second week.

Despite the upsets, several top-tier women’s seeds maintained their trajectory. Elena Rybakina, the No. 3 seed, defeated No. 27 Marta Kostyuk 6-3, 6-4 in a match defined by Rybakina’s dominant service games. Fifth-seeded Jessica Pegula also enjoyed a straightforward afternoon, dismissing No. 26 Leylah Fernandez with a double 6-2 scoreline. Pegula converted four of her six break-point chances while successfully defending all three break points she faced. These victories set up a high-stakes fourth-round schedule that features a mix of established veterans and surging underdogs.

The departure of Alcaraz remains the primary talking point of the tournament, given his status as the current holder of a career Grand Slam. His 2024 season had been nearly flawless until the recent weeks in the United States. For Korda, the result serves as a validation of his tactical adjustments and physical conditioning. As the tournament progresses toward the quarterfinals, the pressure intensifies for the remaining seeds to avoid the same fate that befell the world No. 1. The Miami Open continues with fourth-round action scheduled for Monday, featuring both the men's and women's remaining contenders.
