Four-time Grand Slam champion Naomi Osaka reached the fourth round of the Canadian Open with a dominant win over 22nd-seed Jelena Ostapenko.
The unseeded 27-year-old was impressive in the 6-2 6-4 success and will face a last-16 tie with a second successive Latvian in Anastasija Sevastova.
Japan's Osaka, a winner twice at the US and Australian Opens, will meet Sevastova after the 35-year-old upset defending champion, and third seed, Jessica Pegula 3-6 6-4 6-1 in Montreal on Friday.
Now ranked 49th in the world, Osaka has not reached the quarter-final of a Grand Slam or WTA 1000 event since returning from maternity leave at the start of 2024.
