“I Can’t Believe I Did That”: Sebastian Korda Stuns World No.1 Carlos Alcaraz in Miami Epic
American scores biggest win of career, ends Alcaraz’s 16-1 start to 2026 and hands Spaniard earliest loss of the season
March 22, 2026 | 4 min read
MIAMI GARDENS, Fla. — Sebastian Korda stood on Stadium Court, hands on his head, staring at the scoreboard. 6-3, 5-7, 6-4. Against Carlos Alcaraz. The world No.1.
The 25-year-old American had just done something no one else had managed in 2026.
He beat Alcaraz before the quarterfinals.
“It’s a dream,” Korda said afterward, still catching his breath after two hours and 18 minutes of high-wire tennis. “To beat the best player in the world on a court like this, in front of this crowd… I can’t believe I did that.”
The Man Who Ended Alcaraz’s Dominance
| Alcaraz’s 2026 Before Miami | Record |
|---|---|
| Australian Open | Champion |
| Qatar Open | Champion |
| Indian Wells | Semifinalist |
| Combined record | 16-1 |
Alcaraz entered Miami as the most dominant player on tour. He’d already won two titles, completed the Career Grand Slam in Melbourne, and saw his 16-match winning streak end only in the Indian Wells semifinals against Daniil Medvedev .
Against Korda, he looked vulnerable from the start.
| Set | Korda | Alcaraz | Key Moment |
|---|---|---|---|
| 1st | 6 | 3 | Korda saves two break points, breaks late |
| 2nd | 5 | 7 | Alcaraz wins 5 straight games after Korda serves for match |
| 3rd | 6 | 4 | Korda breaks, holds nerve, serves it out |
The first set: Korda, seeded 32nd, announced his intentions early. He saved two break points in the third game, then broke Alcaraz to close the set. The world No.1 looked unsettled.
The second set: Korda threatened to run away, winning three straight games and earning a chance for a double-break lead. Then came the collapse. Serving for the match at 5-3, Korda was broken at love. Alcaraz reeled off five straight games, stealing the set 7-5.
The third set: This was where Korda showed his maturity. Down 3-5 in the second, he’d seen Alcaraz turn the match. He didn’t crumble. He broke early, held his nerve, and served out the match—this time without hesitation.
| Stat Category | Korda | Alcaraz |
|---|---|---|
| Aces | 8 | 4 |
| Break points saved | 4/7 | 4/6 |
| Winners | 32 | 29 |
| Unforced errors | 28 | 31 |
| First serve % | 64% | 61% |
The margin was razor-thin. But Korda was just better when it mattered .
Korda’s career has been defined by flashes of brilliance interrupted by injury. A former world No. 15, he’s struggled to stay on the court. But he’s always played his best in Miami—two previous quarterfinal runs at Hard Rock Stadium—and arrived this year with a title in Delray Beach .
Against Alcaraz, he played with nothing to lose.
“I knew I had to be aggressive,” Korda said. “If you let Carlos dictate, you’re done. I just went for my shots.”
What This Means
| Impact | Details |
|---|---|
| For Korda | Biggest win of career, first Top 3 win since 2023 (Medvedev, Shanghai) |
| For Alcaraz | Earliest loss since Paris Masters (November 2025) |
| For the draw | Wide open—Alcaraz’s quarter is now without its top seed |
| For American tennis | A statement win at a home 1000 event |
Korda’s previous best win was against then-No. 3 Daniil Medvedev at the 2023 Shanghai Masters. This was bigger .
What’s Next
Korda advances to the fourth round, where he’ll face either No. 14 seed Karen Khachanov or Spanish qualifier Martín Landaluce.
“I’ve got to recover and get ready for the next one,” Korda said. “But tonight? I’m going to enjoy this.”
He earned it.
