Canadian Bianca Andreescu advanced to the quarterfinals of the Toray Pan Pacific Open in Tokyo on Wednesday after a back injury forced second seed Beatriz Haddad Maia of Brazil to withdraw.

Andreescu led 3-0 at the end of the match with Haddad Maia clearly in pain. After several setbacks and many stoppages due to his own injuries, he is looking for the fourth title of his career. The previous three all took place in 2019, and this will be her first quarterfinal at the WTA 500 level or above since 2022.

Another Canadian also advanced to the quarterfinals when Leylah Fernandez beat No. 8 seed Varvara Gracheva of France 6-0, 3-6, 7-5. No. 6 seed Diana Shnaider of Russia had no trouble with Bulgaria's Viktoriya Tomova in a 6-2, 6-2 victory. Shnaider will next face Sayaka Ishii after the Japanese qualifier beat Türkiye Zeynep Sonmez 4-6, 6-2, 6-3.
