Sebastian Korda (32) def. Carlos Alcaraz (1) 6-3, 5-7, 6-4
The most important shock of the event 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 participant (No. 36) to beat Alcaraz since David Goffin (No. 55) in Miami final yr.

The American has all the time been in a position to strike a really clear ball off each wings, however he’s had a good few wrist issues, so his tennis has been fairly stop-start. Nevertheless, he has performed six consecutive tournaments within the US and performed an incredible match.
Alcaraz didn’t play poorly; he simply wasn’t at his greatest, and Korda’s flatter hitting works effectively in these situations.

He improved to 5-0 H2H vs Tsitsipas, underscoring simply how a lot H2H issues in tennis. Tstitsipas has been woeful for effectively over a yr now, but he took out High 10 De Minaur simply within the spherical earlier (11-1 H2H), solely then to get destroyed by Fils, who has an ideal file towards 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 spherical with authority, hitting 25 winners to Khachanov’s 12 and successful 78% of first-serve factors in 1 hour 32 minutes.
