Details

We estimate Renta Tokuda to be the clear favorite based on the provided profiles: Tokuda (46-16 career, strong results on hard courts) vs Matsuoka (14-26, weaker form). The market price of 1.283 implies an implied win probability of ~77.9% (1/1.283). Given Tokuda's superior win rate, heavy hard-court usage and recent positive form shown in the research, we estimate his true win probability at 82%. At that probability the fair price is 1.220 (1/0.82); the bookmaker price 1.283 therefore contains value. Calculation: EV = p * decimal_odds - 1 = 0.82 * 1.283 - 1 = 0.052 (≈5.2% ROI). Primary uncertainties are limited H2H detail and the relatively small sample for both players, but the differential in career records and surface experience supports backing the home player at the quoted price.

Key factors

• • Tokuda's substantially better career win-loss record and heavy hard-court experience
• • Market implied probability (77.9%) is below our estimated true probability (82%)
• • Matsuoka's losing record and weaker recent form reduce his upset likelihood
