Overview

• Osaka confirmed on July 28 via Instagram that she had ended her 10-month partnership with Patrick Mouratoglou.
• She immediately invited Iga Swiatek’s former coach, Tomasz Wiktorowski, to join her team on a trial basis at the Canadian Open in Montreal.
• Under Wiktorowski’s guidance on court, Osaka overturned a one-set deficit and saved three match points to beat Liudmila Samsonova 4-6, 7-6(6), 6-3.
• Wiktorowski’s credentials include leading Swiatek to four Grand Slam titles, 125 weeks at world No. 1, and a 37-match winning streak.
• Osaka’s ranking has slipped to No. 49 since her 2024 maternity comeback, driving a rapid series of provisional coaching changes aimed at restoring her Grand Slam form.
