Korda Stuns World Number One Alcaraz at Miami Open

Sebastian Korda delivered one of the Miami Open’s most stunning upsets 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, secured his career-best scalp in 2h 19m, becoming the lowest-ranked man to beat the Spanish top seed since David Goffin achieved the feat last year. Alcaraz, who began 2026 with his seventh Grand Slam title at the Australian Open, struggled with an unusually poor opening set before mounting a spirited comeback that ultimately fell short. The result represents only Korda’s second victory against Alcaraz in their six meetings, confirming a career-defining display that sends the 25-year-old American through to face either 14th seed Karen Khachanov or qualifier Martin Landaluce in the fourth round.

Korda’s Landmark Victory

Sebastian Korda’s triumph over Alcaraz represented a turning point in his professional career, offering the kind of victory that can dramatically change competitive momentum and self-belief. The American had made it to the last eight of Miami previously, in 2021 and 2025, but had not advanced further in the tournament. In his match against the world’s best player, Korda demonstrated the mental strength and composure necessary at the highest level, especially in the crucial moments when the result was in doubt. His skill in recovering from failing to convert a match point at 5-4 in the next set demonstrated a composure that belied his current ranking and implied he demonstrates the mental fortitude to take on elite competitors consistently.

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.

Match Development

Initial Set Superiority

Alcaraz’s Miami campaign unravelled almost immediately, with the world number one producing a unexpectedly careless opening set that gifted Korda the initial edge. The Spanish number one appeared unusually erratic, 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 identified weaknesses in his rival’s play that could be exploited throughout the match.

The early dominance proved vital in building Korda’s conviction and self-assurance against a opponent he had previously found difficult. By taking the first set with ease, the 25-year-old American signalled his intent and proved that he had the tools to test even the top players. This initial triumph provided a mental platform upon which Korda could establish his advantage, though the match remained far from decided as Alcaraz readied his inevitable response in the following set.

Second Set Dispute

The second set evolved into a intense struggle of nerves and skill, with both players exchanging momentum and openings in a captivating display of modern tennis. Korda seemed positioned to assume full dominance when he got to 5-4 and played for the title, seemingly a single game away from a remarkable win. However, Alcaraz produced a crucial break of serve, claiming the game to love and showcasing the fighting spirit that has shaped his path. The Spaniard’s fightback proved decisive, as he subsequently won the following two games to push the match into a final set.

This striking reversal demonstrated the mental toughness that Alcaraz has continually exhibited throughout his career, even as his rival sought to conclude proceedings early. The change in fortunes came at the perfect juncture for the top-ranked player, offering a reprieve when victory looked unlikely. Yet Korda’s capacity to stay calm despite squandering a golden opportunity would prove equally significant, laying the groundwork for an tense deciding set where both players possessed the emotional fortitude to triumph.

Pivotal Third Set

The third set turned the match as Korda took command and took advantage when it mattered most. At 4-3, with Alcaraz serving, the American secured the break when his opponent’s forehand drifted out. This break represented the turning point, as Korda maintained his composure to comfortably serve out the remaining games with clinical precision and unwavering focus. The American’s capacity to stay calm under intense pressure ultimately proved the difference 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, unable to cope with the American’s sustained pressure. The finish exemplified Korda’s controlled performance in the final set, where he showed the mental fortitude and technical excellence required to defeat the top-ranked player. This comprehensive closing phase highlighted that Korda’s victory was no fluke, but rather the product of relentless excellence and unwavering self-belief throughout an gripping encounter.

Alcaraz’s View on Defeat

Despite the frustrating loss, Alcaraz maintained a pragmatic view regarding his showing at the Miami Open. The top-ranked player noted that his overall process stays sound, arguing that he is moving in the proper trajectory despite this surprising third-round exit. Alcaraz acknowledged that certain elements of his play felt awkward in earlier events, but he has begun to feel increasingly at ease as the Miami tournament developed. His composed outlook demonstrated a player dedicated to sustained improvement rather than fixating on individual defeats, particularly with the clay season drawing near.

The Iberian titleholder underscored the distinctive characteristics when lower-ranked opponents encounter top players, noting that competitors like Korda possess the mental edge of having more to gain than lose. Alcaraz emphasised that these competitors naturally operate without the burden of expectation, enabling them to compete with greater freedom and attacking intent. He was keen to stress that he does not feel pressure himself, rather focusing on delivering his finest tennis. This perspective reflects Alcaraz’s sophisticated mindset to setbacks, viewing them as learning opportunities rather than reflections of his capability or career path.

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

Women’s Singles Improvement

Third seed Elena Rybakina advanced to the last 16 of the women’s singles tournament with a impressive 6-3 6-4 win against Ukraine’s Marta Kostyuk. The Russia-born Kazakhstani player demonstrated clinical precision throughout the encounter, securing her passage into the next round comfortably. Rybakina will now take on Australian prospect Talia Gibson, who has experienced a strong performance through the tournament. Gibson has already posted an impressive win, beating 18th seed Iva Jovic with a emphatic 6-2 6-2 showing, extending an excellent form that saw her reach the semi-finals at Indian Wells.
