The women's draw also sees Elena Rybakina of Kazakhstan, the No. 3 seed, beat Jessica Pegula of the USA 6-1, 6-3. These matches set up high-profile clashes: Sabalenka faces Noskova and Rybakina takes on Victoria Azarenka (not explicitly stated but implied by context of semi-finals). The men's semi-finals feature Arthur Rinderknech of France and Marcel Granollers of Spain.

Rinderknech, seeded 1, defeated Jackson Withrow of the USA 6-4, 6-7(5), 10-5 in a grueling match. Granollers, also seeded 1, beat Manuel Guinard of France 6-4, 6-4. These results shift the tournament landscape significantly for the final four, with top seeds advancing.

The ATP Challenger events also produced winners, including Corentin Moutet of France and Michael Geerts of Belgium, who advanced to semi-finals in their respective events.
