Korda Stuns World Number One Alcaraz at Miami Open

Sebastian Korda produced one of the Miami Open’s most stunning upsets on Saturday, eliminating 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 finest career win in 2h 19m, becoming the lowest-ranked man to beat the Spanish top seed since David Goffin achieved the feat last year. Alcaraz, who started the year with his seventh major championship at the Australian Open, battled against an uncharacteristically sloppy opening set before launching a determined fightback that ultimately fell short. The result marks only Korda’s second victory against Alcaraz in their six encounters, cementing a career-defining display 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 Breakthrough Win

Sebastian Korda’s victory against Alcaraz constituted a turning point in his tennis career, offering the type of win that can substantially alter momentum and confidence. The American had reached the quarter-finals of Miami on two previous occasions, in 2021 and 2025, but had never progressed further in the tournament. In his match against the world’s best player, Korda demonstrated the mental strength and composure required at the highest level, most notably during the crucial moments when the match hung in the balance. His skill in recovering from failing to convert a match point at 5-4 in the next set revealed a sophistication that contradicted his seeding and indicated he has 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 the Match Unfolded

Opening Set Control

Alcaraz’s Miami campaign fell apart very quickly, with the world number one producing a unexpectedly careless opening set that gifted Korda the early advantage. The Spanish top seed looked uncharacteristically loose, making unforced errors that allowed the American to take charge and dictate proceedings from the baseline. Korda took full advantage on Alcaraz’s poor form, securing the first set 6-3 with a display that suggested he had spotted vulnerabilities in his rival’s play that could be exploited throughout the match.

The initial superiority proved crucial in building Korda’s conviction and self-assurance against a opponent he had previously found difficult. By winning the opening set convincingly, the 25-year-old American demonstrated his determination and showed that he possessed the weaponry to test even the world’s elite. This initial triumph provided a mental platform upon which Korda could build, though the match remained far from decided as Alcaraz prepared to mount his inevitable response in the following set.

Second Set Drama

The second set developed into a thrilling battle of composure and ability, with both players exchanging momentum and opportunities in a captivating display of modern tennis. Korda appeared poised to take complete command when he got to 5-4 and played for the title, seemingly just one game away from a impressive triumph. However, Alcaraz produced a crucial break of serve, snatching the game to love and demonstrating the competitive drive that has defined his career. The Spaniard’s recovery proved pivotal, as he subsequently won the next two games to push the match into a deciding third set.

This remarkable comeback demonstrated the fortitude that Alcaraz has consistently shown throughout his career, even as his rival sought to finish matters ahead of schedule. The change in fortunes came at exactly the ideal time for the top-ranked player, offering a second chance when defeat appeared imminent. Yet Korda’s ability to remain composed despite squandering a golden opportunity would prove equally important, preparing the scene for an intense final set where both players showed the emotional fortitude to succeed.

Critical Final Set

The third set proved decisive as Korda reasserted his authority and capitalised on the key opportunity. At 4-3, with Alcaraz serving, the American secured the break when his opponent’s forehand drifted out. This break proved the decisive moment, as Korda maintained his composure to confidently finish the remaining games with sharp execution and resolute determination. The American’s ability to maintain composure under mounting pressure ultimately decided the outcome between victory and defeat.

Korda finished the match in 2 hours 19 minutes, securing the win on his second opportunity when Alcaraz overhit a return, unable to cope with the American’s sustained pressure. The finish epitomised Korda’s controlled performance in the closing set, where he showed the psychological strength and technical mastery required to defeat the top-ranked player. This dominant final stretch emphasised that Korda’s victory was no fluke, but rather the product of consistent excellence and unwavering self-belief throughout an gripping encounter.

Alcaraz’s Thoughts on Defeat

Despite the disappointing loss, Alcaraz maintained a pragmatic view regarding his showing at the Miami Open. The top-ranked player suggested that his fundamental strategy remains sound, insisting that he is progressing in the correct path despite this unforeseen third-round exit. Alcaraz recognised that certain elements of his play felt unsettling in past competitions, but he has begun to feel increasingly at ease as the Miami competition progressed. His balanced reaction showed a player focused on ongoing progress rather than fixating on individual setbacks, particularly with the clay events looming on the horizon.

The Spanish champion underscored the unique dynamics when players ranked below face top players, observing that players such as Korda have the mental edge of standing to gain more than they risk losing. Alcaraz emphasised that these competitors naturally operate without the burden of expectation, allowing them to play with more freedom and aggressive intent. He was keen to stress that he doesn’t experience pressure himself, rather focusing on delivering his finest tennis. This perspective demonstrates Alcaraz’s mature approach to defeats, treating them as chances to improve rather than reflections of his capability or career path.

• Alcaraz claimed his seventh Grand Slam at the Australian Open earlier this year
• His opening defeat of the season came against Daniil Medvedev at Indian Wells
• Korda is the lowest-ranked competitor to beat Alcaraz since David Goffin in 2025

Women’s Singles Progress

Third seed Elena Rybakina reached the last 16 of the women’s singles championship with a convincing 6-3 6-4 victory over Ukraine’s Marta Kostyuk. The Russia-born Kazakhstani player displayed clinical efficiency during the match, securing her passage into the next round without significant difficulty. Rybakina will now face Australian qualifier Talia Gibson, who has had a strong performance in the competition. Gibson has already claimed a notable scalp, beating 18th seed Iva Jovic with a commanding 6-2 6-2 showing, continuing an impressive stretch that saw her make the quarter-finals at Indian Wells.
