TORONTO - Naomi Osaka is hoping her success last year in Montreal, where she finished runner-up to Victoria Mboko, will translate as the WTA's 1000 event in Canada shifts to Toronto. Osaka earned the last of her four major titles at the 2021 Australian Open and has yet to regain the heights she reached before taking an extended maternity leave in 2023. But she made it to the US Open semi-finals last year and reached the last 16 at the French Open for the first time this year before a career-best quarter-final at Wimbledon. Osaka is in the same quarter as second-seeded Australian Open champion Elena Rybakina and in the fourth round she could find herself up against fifth-seeded French Open champion Mirra Andreeva. After disappointing runs at the French Open and Wimbledon the Belarusian is aiming to reassert her dominance on hard courts, where her lone defeat this year was to Rybakina in the Australian Open final.
