Details

The market price for Yuta Kawahashi (1.182 decimal) implies a win probability of ~84.6%. Kawahashi has a substantially stronger record and form context vs Xing Dao Chen (Kawahashi: 19-17 in 36 matches; Chen: 5-17 in 22 matches) and both players have experience on hard courts, which reduces surface-based uncertainty. Chen's very low win rate and recent string of losses suggest a markedly lower chance to upset at this stage (semifinal). Given those factors we estimate Kawahashi's true win probability at 87.0%, higher than the market-implied 84.6%, producing a small positive edge. Downsides: Kawahashi is not an overwhelming long-term performer (career win rate near 53%), sample sizes are modest, and we lack H2H detail—so the edge is modest and susceptible to variance. Calculation: EV = p * odds - 1 = 0.87 * 1.182 - 1 = 0.028 (2.8% ROI on a 1-unit stake).

Key factors

• • Kawahashi has a substantially better win-loss record (19-17) vs Chen (5-17)
• • Both players have experience on hard courts, mitigating surface uncertainty
• • Market implied probability (84.6%) is slightly below our 87% estimate, creating a small edge
