The American scored the biggest win of his career—and handed Alcaraz his earliest loss of the season.

The tennis world witnessed a seismic shift at the 2026 Miami Open as Sebastian Korda pulled off the biggest upset of the tournament, dethroning the seemingly invincible world No. 1, Carlos Alcaraz. This wasn't just a win; it was a resounding statement from the American.

Key Match Points

  • Sebastian Korda stunned Carlos Alcaraz (6-3, 5-7, 6-4) in a grueling third-round battle on Stadium Court.
  • This monumental victory marks Alcaraz's earliest exit of the 2026 season, shattering his dominant 16-1 record.
  • A career-defining moment for the American talent, who previously held a 1-6 record against Top 3 players.
  • Korda's exceptional record at the Hard Rock Stadium continues, proving his comfort on these courts.

Alcaraz's Unstoppable Reign Interrupted

Heading into the Miami Open, Carlos Alcaraz was in a league of his own. The world No. 1 had compiled an astonishing 16-1 record, claiming the Australian Open—making him the youngest male to complete the Career Grand Slam—and adding another title at the Qatar ExxonMobil Open. His only prior hiccup was a semifinal loss at BNP Paribas.

Alcaraz arrived in Miami full of confidence, swiftly dispatching Joao Fonseca in his opening match. Few expected him to stumble so early, especially against an opponent who had largely struggled against the game's elite.

Korda's Resurgence: Miami Magic Continues

Across the net stood Sebastian Korda, a player whose immense talent has often been overshadowed by injury setbacks. Despite previously reaching world No. 15, consistent top-level performances have been elusive. However, Miami has always been a special place for Korda, where he's made two previous quarterfinal runs.

He entered this tournament rounding into peak form, fresh off a title victory in Delray Beach. His dominant opening-round win, dropping only three games against Camilo Ugo Carabelli, signaled his intent. The stage was set for an epic clash, and Korda delivered.

A Battle of Wills: Analyzing the Three-Set Epic

The match on Stadium Court was a testament to both players' resilience. Korda seized the initiative early, saving two crucial break points in the third game before breaking Alcaraz himself to comfortably take the opening set 6-3. He looked poised for a quick victory.

Korda then threatened to run away with the second set, winning three consecutive games and earning a chance for a double-break. But champions find a way, and Alcaraz clawed back, securing a love-break when Korda served for the match, then reeling off five straight games to force a decisive third set. The momentum had visibly swung.

Composure Under Pressure: Korda Seals the Deal

Undeterred by Alcaraz's furious comeback, Korda showed incredible mental fortitude. He immediately snapped Alcaraz's streak, getting back on the board and then earning the first break of the final set. He withstood Alcaraz's desperate attempts to level the score.

Serving for the match a second time at 5-4, Korda made no mistake. He executed flawlessly, putting away a backhand to earn two match points. Though Alcaraz valiantly saved the first, Korda unleashed one final, perfectly struck serve to claim the biggest win of his career.

What's Next for the American Star?

This victory propels Sebastian Korda into the fourth round, where he will face either the experienced No. 14 seed Karen Khachanov or Spanish qualifier Martín Landaluce. The tennis world will be watching to see if Korda can build on this monumental upset and continue his magical run at the 2026 Miami Open.
