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 defeating the Latvian 6-2 6-4 and could next face American third seed Jessica Pegula in the last 16.
Japan's Osaka, a winner twice at the US and Australian Opens, will meet either Pegula or a second successive Latvian in Anastasija Sevastova as they face each other on Friday.
Now ranked 49th in the world, she has not reached the quarter-final of a Grand Slam or WTA 1000 event since returning from maternity leave at the start of 2024.
But Osaka impressed by winning the first set in 30 minutes before moving 3-1 ahead in the second.
She broke again for a 4-2 lead when Ostapenko netted a forehand and served for the match at 5-3.
But her 28-year-old opponent saved a match point on a forehand crosscourt winner and broke back when Osaka sent a forehand beyond the baseline.
Ostapenko, though, was broken again to love in the final game, with the Latvian netting a backhand to conclude matters after an hour and 12 minute.
Britain's Emma Raducanu is also in action later, when she takes on American fifth seed Amanda Anisimova.
