Jessica Pegula was dethroned at the Montreal, Canada, tennis tournament. The champion of the last two years suffered a surprise upset at the hands of unseeded Anastasija Sevastova, losing in the third round 6-3, 4-6, 1-6 in just over an hour and 40 minutes of play.

The match started strongly for the third-seeded Pegula, who made two breaks and won the opening set 6-3. The American also broke early in the second set, but then suffered an unexpected collapse and Sevastova pulled ahead 4-2. Pegula returned the break, but was broken in the ninth game by the Latvian No. 386 in the world. Sevastova later survived to level the score after trailing 0-40 on her own serve. Pegula squandered three more break points in the second game of the third set and was instantly broken, and then there was no turning back.

Sevastova will next play Naomi Osaka, who defeated 22nd-seeded Jelena Ostapenko.

Second-seeded Iga Swiatek overcame Eva Lys of Germany to set up a clash with Dane Clara Tauson. In the lower half, the remaining two last-16 matches are also very intriguing - last year's finalist Amanda Anisimova vs. Elina Svitolina and Australian Open champion Madison Keys vs. Karolina Muchova. | BGNES
