Key Matches
Sebastian Korda (32) def. Carlos Alcaraz (1) 6-3, 5-7, 6-4
The biggest shock of the tournament was Seb Korda took out the World No. 1 in a 2-hour-19-minute thriller, marking his first win over a World No. 1 and the lowest-ranked player (No. 36) to beat Alcaraz since David Goffin (No. 55) in Miami last year.
Korda dominated early (75% first serves in, 5 aces in set 1), but faltered when serving for the match at 5-4 in the second, dropping five straight games to Alcaraz. He regrouped brilliantly in the decider with clean ballstriking and composure.
Korda called it a “scenic route” win after soul-searching and new coaching input (Ryan Harrison). This ends Alcaraz’s 16-0 start to 2026 (now 17-2), opening the door for Jannik Sinner in the No. 1 race.
The American has always been able to strike a very clean ball off both wings, but he’s had a fair few wrist problems, so his tennis has been pretty stop-start. However, he has played six consecutive tournaments in the US and played a great match.
Alcaraz didn’t play poorly; he just wasn’t at his best, and Korda’s flatter hitting works well in these conditions.
Arthur Fils (28) def. Stefanos Tsitsipas 6-0, 6-1
A masterclass as Fils obliterated Tsitsipas in just 55 minutes, winning 89% of first-serve points, saving both break points, and forcing 28 unforced errors from the Greek. Fils called it “one of the best matches I’ve ever played” and declared himself “fully back” after a back injury ended his 2025 season.
He improved to 5-0 H2H vs Tsitsipas, underscoring just how much H2H matters in tennis. Tstitsipas has been woeful for well over a year now, yet he took out Top 10 De Minaur easily in the round previous (11-1 H2H), only then to get destroyed by Fils, who has a perfect record against him.
Martin Landaluce (Q) def. Karen Khachanov (14) 6-3, 7-6(2)
Milestone for the 20-year-old Spaniard as Landaluce reached his first ATP Masters 1000 fourth round with authority, hitting 25 winners to Khachanov’s 12 and winning 78% of first-serve points in 1 hour 32 minutes.
Other Matches
- Taylor Fritz (6) def. Reilly Opelka 6-3, 6-4. All-American battle won by the seed. Fritz advanced comfortably over the big-serving Opelka.
- Jiri Lehecka (21) def. Ethan Quinn 6-3, 7-6(6). The Czech seed ended the American’s impressive run (which included upsets of Hurkacz and Ruud earlier).
- Tommy Paul (22) def. Raphael Collignon 6-2, 3-6, 7-6(5). Tight decider; Paul edged the tiebreak after dropping the second set to the upset specialist (who beat Dimitrov and Cobolli).
- Valentin Vacherot (24) def. Matteo Berrettini 7-6(5), 6-4. The Monegasque (2025 Shanghai champ) notched his 10th win of 2026 and reached R16 at three of his last four Masters 1000s.
