In this upcoming match, Nam appears to have a slight edge over Roh based on their recent statistics. Nam demonstrates superior performance in second serve points and return games compared to Roh, which are critical indicators for predicting match outcomes.
While Roh has shown resilience under pressure by saving a higher percentage of breakpoints, Nam has maintained more consistent success in overall matches won during the past year.
