Clara Tauson advances to NBO semifinals with straight-sets win over Madison Keys

By Canadian Press on August 5, 2025.

MONTREAL — Clara Tauson is heading to the National Bank Open semifinals.

The 22-year-old from Denmark advanced to the final four with a 6-1, 6-4 win over Madison Keys of the United States in the women’s singles quarterfinals Tuesday.

Tauson, seeded 16th, dominated from start to finish, converting three of six breakpoint opportunities while saving all three she faced against the sixth-seeded Keys.

Tauson also knocked out world No. 3 Iga Swiatek 7-6 (1), 6-3 in the fourth round and hasn’t lost a set at the WTA 1000 event.

The top eight seeds are now out of the 96-player tournament after Keys’s exit.

Tauson will face the winner of Tuesday’s late match between No. 10 seed Elina Svitolina of Ukraine and Naomi Osaka of Japan at IGA Stadium.

Canadian teenage sensation Victoria Mboko takes on ninth seed Elena Rybakina of Kazakhstan in the other semifinal Wednesday. Mboko, who’s playing in her first main draw at the National Bank Open, will rise into the WTA’s top 50 after beginning the year outside the top 300.

The 18-year-old from Toronto has defeated five higher-ranked opponents en route to the semifinals, including top seed and world No. 2 Coco Gauff in the fourth round.
