Naomi Osaka lost just one game as she outplayed Anastasija Sevastova to reach the Canadian Open quarter-finals in Montreal.
The four-time Grand Slam champion took just 49 minutes to wrap up a 6-1 6-0 victory against the 35-year-old Latvian, who had knocked out defending champion Jessica Pegula in the previous round.
Japan's Osaka, a winner twice at the US and Australian Opens, is seeking her first title since returning from maternity leave early in 2024.
The 27-year-old parted with coach Patrick Mouratoglou after less than a year and is now working with Poland's Tomasz Wiktorowski, former coach of Iga Swiatek.
