Evaluating their recent performances, both players present a strong case, each possessing distinct advantages. Sinclair's proficiency in under-pressure situations, demonstrated by a higher breakpoint save percentage, could prove pivotal during tightly contested moments.

Conversely, Isomura's ability to generate opportunities through substantial return game stats indicates a compelling edge, notably winning a higher percentage of first and second serve return points.
