Sebastian Korda produced one of the Miami Open’s most remarkable victories on Saturday, defeating world number one Carlos Alcaraz in the third round with a dominant 6-3 5-7 6-4 victory. The American, sitting 36th in the world rankings, claimed his career-best scalp in 2h 19m, becoming the lowest-ranked man to defeat the Spanish top seed since David Goffin accomplished the same result last year. Alcaraz, who began 2026 with his seventh major championship at the Australian Open, struggled with an uncharacteristically sloppy opening set before mounting a spirited comeback that came up just short. The result marks only Korda’s second win against Alcaraz in their six meetings, confirming a breakthrough performance that sends the 25-year-old American into a matchup with either 14th seed Karen Khachanov or qualifier Martin Landaluce in the fourth round.
Korda’s Landmark Victory
Sebastian Korda’s victory against Alcaraz constituted a turning point in his professional career, offering the calibre of performance that can fundamentally shift momentum and confidence. The American had made it to the quarter-finals of Miami twice before, in 2021 and 2025, but had never progressed further in the competition. Against the world’s best player, Korda demonstrated the composure and mental fortitude required at the top level, most notably during the pivotal stages when the match hung in the balance. His capacity to bounce back from squandering a match point at 5-4 in the next set showcased a maturity that belied his ranking and indicated he demonstrates the mental fortitude to challenge elite players with regularity.
Korda’s path to victory required navigating several treacherous passages, most notably when serving for the match at 5-4 in the second set only to be broken to love by Alcaraz, who subsequently won two consecutive games to force a decider. Yet rather than wilting under the pressure, Korda regrouped and seized the decisive break in the third set when Alcaraz’s forehand sailed wide at 4-3. The American then held his nerve to close out the remaining service games with clinical precision, ultimately sealing victory when Alcaraz overhit a return on the second match point. This composure under duress proved the defining characteristic of his performance.

How Events Unfolded
Opening Set Control
Alcaraz’s Miami campaign unravelled almost immediately, with the top-ranked player delivering a unexpectedly careless opening set that handed Korda the initial edge. The Spanish number one looked unusually erratic, making mistakes under no pressure that allowed the American to establish control and control play from the baseline. Korda took full advantage on Alcaraz’s struggling performance, securing the first set 6-3 with a performance that suggested he had identified weaknesses in his rival’s play that could be exploited throughout the match.
The initial superiority proved vital in building Korda’s belief and confidence against a player he had previously struggled against. By taking the first set with ease, the 25-year-old American signalled his intent and showed that he had the tools to trouble even the top players. This initial triumph created a mental platform upon which Korda could build, though the match remained far from decided as Alcaraz prepared to mount his expected comeback in the second set.
Second Set Tension
The second set evolved into a thrilling battle of nerves and skill, with both players trading momentum and opportunities in a captivating display of today’s game. Korda looked set to seize complete control when he reached 5-4 and went for the match, seemingly one game away from a stunning victory. However, Alcaraz executed a critical break of serve, taking the game to love and demonstrating the fighting spirit that has characterised his career. The Spaniard’s comeback proved crucial, as he subsequently won the subsequent two games to force the match into a deciding third set.
This remarkable comeback showcased the mental toughness that Alcaraz has consistently shown throughout his professional journey, even as his opponent threatened to finish matters ahead of schedule. The momentum shift came at precisely the right moment for the world number one, offering a lifeline when loss seemed inevitable. Yet Korda’s ability to stay calm despite missing a clear opening would prove equally important, preparing the scene for an tense deciding set where both players showed the mental strength to succeed.
Critical Final Set
The third set became the pivotal moment as Korda took command and seized the critical moment. At 4-3, with Alcaraz serving, the American broke through when his opponent’s forehand drifted out. This break marked the shift in momentum, as Korda kept his focus to confidently finish the remaining games with sharp execution and steady concentration. The American’s skill in managing pressure under sustained pressure ultimately separated the two players between victory and defeat.
Korda concluded the match in 2 hours 19 minutes, sealing victory on his second opportunity when Alcaraz struck too hard a return, struggling against the American’s relentless pressure. The final outcome demonstrated Korda’s controlled performance in the final set, where he exhibited the mental resilience and technical excellence required to defeat the top-ranked player. This comprehensive closing phase emphasised that Korda’s victory was no mere accident, but rather the outcome of sustained excellence and steadfast confidence throughout an enthralling contest.
Alcaraz’s View on Defeat
Despite the disheartening loss, Alcaraz took a pragmatic view regarding his display at the Miami Open. The world number one noted that his fundamental strategy stays sound, arguing that he is moving in the proper trajectory despite this surprising third-round exit. Alcaraz recognised that certain aspects of his game felt awkward in earlier events, but he has started to become increasingly confident as the Miami competition progressed. His composed outlook reflected a player focused on sustained improvement rather than preoccupied with individual setbacks, particularly with the clay season looming on the horizon.
The Spanish champion underscored the distinctive characteristics when lower-ranked opponents encounter elite competitors, noting that players such as Korda possess the mental edge of standing to gain more than they risk losing. Alcaraz stressed that such players naturally operate without the burden of expectation, allowing them to play with greater freedom and attacking intent. He was keen to stress that he does not feel pressure himself, rather focusing on executing his best tennis. This outlook demonstrates Alcaraz’s sophisticated mindset to defeats, viewing them as learning opportunities rather than reflections of his capability or career path.

- His first loss of the season occurred against Daniil Medvedev at Indian Wells
