As we examine second serve performance, Isomura holds a slight advantage, a factor that generally aligns with successful match predictions. Furthermore, Isomura also shows strength in return games, especially against the opponent's second serves, which could prove decisive.

Analyzing past year performance, Isomura edges ahead with a marginally better win percentage. Moreover, in high-pressure situations, Isomura again demonstrates slight superiority in saving breakpoints and performance in deciding sets.

Given these evaluations, despite Matsuoka's notable competitiveness on certain surfaces and in breakpoint scenarios, Isomura appears to have a minor yet consistent overall edge across critical statistics.

Considering these factors, Isomura is predicted to be the more likely victor in the upcoming match.
