MONTREAL – Anastasija Sevastova was just trying to survive at the WTA Canadian Open.

Somehow, she stunned two-time defending champion Jessica Pegula 3-6, 6-4, 6-1 on Aug 1 to book a fourth-round clash with Naomi Osaka on Aug 4.

Sevastova, a former world No. 11 now ranked 386th, snapped fourth-ranked Pegula’s 11-match WTA Canada win streak, the longest since Serena Williams reeled off 14 consecutive wins in 2011, 2013 and 2014.

She will try to extend her Montreal run in a round-of-16 meeting with Osaka, a four-time Grand Slam champion from Japan who ousted another Latvian, 22nd seed Jelena Ostapenko, 6-2, 6-4.

“Somehow, I was down 2-0 in the second set and started to play better and better,” Sevastova said.

“Third set I played really good.”

The 35-year-old, who has dealt with injury since returning from maternity leave in February 2024, added: “Just trying to stay on the court as long as possible.”

Pegula, last year’s US Open runner-up in her best Slam showing, was the first woman to win back-to-back Canadian Open titles since Martina Hingis in 1999-2000.

But she has struggled in recent months, dropping her openers at Wimbledon and at Washington last week.

“It was a weird match for me,” the American said. “I felt like I had total control and then I just played a couple of terrible games for, like, three games.

“That totally flipped the momentum of the match, and I went from being up a set and 2-0 to being down very quickly. I don’t really feel like I’m playing great tennis. At times I am, but I feel very up and down, kind of sloppy, which I don’t like. I’ve got to figure it out.”

Osaka, twice a winner at both the US and Australian Opens, is one match away from her first quarter-final run at either a Grand Slam or WTA 1000 event since she returned from maternity leave at the start of 2024.

Now ranked 49th, the Japanese broke on a double fault by Ostapenko to capture the first set in 30 minutes and raced to a 3-1 lead in the second.

They exchanged breaks before Osaka served for the match with a 5-3 lead, but Ostapenko saved a match point and broke when Osaka sent a forehand beyond the baseline.

The Japanese star responded by breaking her opponent at love in the final game.

“I went in there knowing she’s a great player and if I give her a chance she’s going to hit a winner on me, so I just tried to keep my pace and stay as solid as I could,” Osaka said.

In the night session, second-seeded Iga Swiatek – playing her first tournament since winning Wimbledon – raced into the fourth round with a 6-2, 6-2 victory over Germany’s Eva Lys.

The Pole next faces Denmark’s Clara Tauson, who beat Yuliia Starodubtseva 6-3, 6-0.

Australian Open champion Madison Keys, seeded sixth, beat fellow American Caty McNally 2-6, 6-3, 6-3 and will next meet Karolina Muchova, a 6-7 (2-7), 6-2, 6-3 winner over Belinda Bencic. AFP
