Overview

• Osaka ended her 10-month partnership with Patrick Mouratoglou days before the Canadian Open and added Iga Świątek’s former coach Tomasz Wiktorowski on a trial basis.
• Under Wiktorowski’s guidance, she has won four matches in Montreal—defeating Ariana Arseneault, Liudmila Samsonova, Jelena Ostapenko and Anastasija Sevastova—to reach her first quarterfinal at the event since 2019.
• Her 49-minute, 6-1, 6-0 victory over Sevastova marked the second-fastest match win of her career and matched her best WTA 1000 performance since returning from maternity leave.
• Osaka credits Wiktorowski’s direct, decisive coaching style and unexpected humor with clarifying her strategy and boosting her confidence on court.
• A win over Elina Svitolina in the quarterfinals would secure Osaka her first WTA 1000 semifinal since 2022 and likely propel her back into the top-30 rankings.
