Details

We view Koki Matsuda as the value side given the current moneyline pricing. The bookmaker price of 2.87 implies a win probability of ~34.8% for Matsuda, which we believe is underestimating his chances. Both players have similar career win rates on hard courts (Yanki Erel ~66% overall, Koki Matsuda ~62%), but Matsuda specializes on hard courts and the matchup is on a hard surface environment where Matsuda's profile is strong. Erel has a larger match sample and slightly better aggregate results, which likely justifies a favorite status, but the market is over-adjusting toward Erel (implied ~72.6% for the home), which we think overstates the gap. We estimate Matsuda's true win probability at 38% (0.38); at decimal odds 2.87 this yields a positive expected value (EV = 0.38 * 2.87 - 1 ≈ 0.091). Given limited H2H and no reported injuries in the provided research, the edge is primarily derived from surface specialization and the gap between our probability and the bookmaker-implied probability.

Key factors

• • Surface: match on hard courts, which favors Matsuda who predominantly plays hard
• • Market price skew: bookmaker implies ~34.8% for Matsuda vs our 38% estimate
• • Comparable career win rates but smaller sample for Matsuda and hard-court specialization
