Shuai Zhang defeated Petra Martic 7–5, 6–2 in the quarter-final of the WTA 250 Tokyo tournament on hard court. Zhang, the pre-match favourite at 1.73 odds, justified her seeding with a commanding performance that saw her control the second set after a competitive opening frame. Martic, priced at 2.24, could not sustain the intensity required to trouble the Chinese player, who broke through decisively in both sets to advance. The result reinforces Zhang's form on the hard-court swing and sets up a semi-final clash as she continues her campaign in Tokyo.
