M. C. Romios/R. Seggerman vs K. Uesugi/S. Watanabe

Highlights

• • Estimated true home win probability: 64% (fair price ~1.563)
• • Current favorite price (1.49) yields negative expected return

Pros

• + Market correctly identifies a clear favorite; prices are reasonable given uncertainty
• + Conservative stance avoids marginal bets with negative expected value

Cons

• - Lack of match-specific data increases uncertainty in our probability estimate
• - Favorite's short price offers only a small margin; thin edges are not present at current prices

Details

We assessed the market prices (Home 1.49 / Away 2.48) and, in the absence of any match-specific data (surface, recent form, injuries or H2H), applied a conservative estimate for the favorite. We estimate the home pair's true win probability at 64% (0.64) which implies a fair decimal price of ~1.563. At the available home price of 1.49, the expected return would be negative (EV = 0.64*1.49 - 1 = -0.0464, about -4.6% ROI). The away side priced 2.48 also offers negative expectation under the complementary probability (approx. 36% win chance -> EV ≈ -10.7%). Given both sides show negative expected value versus our conservative probabilities, we do not find a value bet and therefore recommend no side. If more match-specific inputs (surface, recent results, injuries, H2H) become available, our probability estimates and recommendation could change.

Key factors

• • Market-implied favorite price (1.49) roughly equals a 67% market probability; we discount slightly for vig and unknowns
• • No match-specific data available (surface, form, injuries, H2H), so we apply a conservative estimate
• • Both sides produce negative EV under conservative true-probability estimates at the quoted prices
