Defending Canadian Open champion Jessica Pegula is out of the Montreal third round after blowing a big lead and picking up a shock 6-3 4-6 1-6 loss to world No. 386 Anastasija Sevastova.
The American, seeded at No. 3 in Montreal, made a strong start as she claimed breaks in the first and ninth games to routinely take the opening set. Up by a set, the defending champion also won the first two games of the second set.
Leading by a set and a break, Pegula appeared to be heading toward a routine straight-set win. But then, Sevastova responded by stunningly winning the next four games. While the American managed to get the break back and level the set to four games apiece, she lost her serve again in the ninth game as the Latvian went 5-4 up before serving out for a decider in the following game.
After failing to capitalize on her early lead, Pegula's game completely collapsed as the world No. 386 won five games in a row from 1-1 in the third set to complete her shock comeback.
386 – Anastasija Sevastova is the 3rd-lowest ranked since the Tier I/WTA-1000 format's introduction in 1990 to defeat a top-5 in such events

Sevastova collects her first top-10 win since beating Serena Williams & And who is her next Montreal rival?
By beating world No. 4 Pegula, Sevastova – a former world No. 11 – registered her first top-10 win since upsetting Serena Williams in the Billie Jean King Cup.
For a place in the Montreal quarterfinal, Sevastova will play against Naomi Osaka, who defeated Jelena Ostapenko today.
So far, they have met five times and Osaka leads their head-to-head 3-2. However, it should be noted that their last match came more than six years ago during the 2019 Australian Open.
