In the other all-American semifinal, a resurgent Amanda Anisimova beat eighth-seeded Emma Navarro 6-3, 2-6, 6-2 in windy afternoon conditions.

The former world No. 21, now ranked No. 132, has beaten four Top 10 players in a row the second-lowest ranked WTA 1000 finalist in history.

After beating No. 1 seed Coco Gauff in the third round, Shnaider, 20, defeated 2023 finalist Liudmila Samsonova in the quarterfinals.

The American, who took a sabbatical from the tour in 2023 to focus on her mental health, is now 5-2 vs. Sabalenka all-time following a 6-4, 6-2 win.

Gauff racked up 42 unforced errors in windy conditions to lose to a player younger than her for the first time in her career.

The No.3 seed joined Amanda Anisimova, Emma Navarro and Taylor Townsend in booking quarterfinal spots on Friday, with Coco Gauff and Peyton Stearns still to play.

The former No. 1 cemented her return to the Top 10 with her biggest title since 2020, and with the US Open right around the corner.

In the last year the 18-year-old has won two WTA 1000s and reached her first two Grand Slam doubles finals.

The Brazilian was on a seven-match winning streak against Top 20 players, but Halep—who’s projected to rise from No. 15 to No. 6 with this title—was just too tough.

The No. 10 seed will now face Simona Halep for a National Bank Open semifinal spot.
