Clara Tauson upsets Wimbledon champion Iga Swiatek to reach Montreal quarterfinals

MONTREAL (AP) — Clara Tauson of Denmark upset second-seeded Wimbledon champion Iga Swiatek of Poland 7-6 (1), 6-3 on Friday night to reach the National Bank Open quarterfinals.

The 6-foot Tauson, seeded 16th in the hard-court event, avenged a loss to Swiatek at Wimbledon to set up a match Tuesday with sixth-seeded Australian Open winner Madison Keys of the United States.

Tauson won her lone tour title in New Zealand in January, beating fellow Montreal quarterfinalist Naomi Osaka of Japan in the final.

Keys outlasted 11th-seeded Karolina Muchova of Czechia 4-6, 6-3, 7-5 in the windy afternoon session.

Osaka also advanced in the afternoon, routing Anastasija Sevastova of Latvia 6-1, 6-0 in 49 minutes — the second-fastest victory of her career. Osaka had a 42-minute victory in a 2016 event in Brazil.
