Similar first-serve return stats, 34.09% for Kaji and 36.1% for Yamazaki, shed light on who might have the upper hand in this encounter.
Facing pressure on the court, how do these players fare? Breakpoint conversion can tell us much. Kaji has saved half of the breakpoints they have faced, a figure that's modestly superior to Yamazaki's 42.78% save rate.
