Highlights

• • Home priced at 1.04 implies >96% chance — requires near-certainty to be profitable
• • Our estimated true probability (92%) produces a -4.32% ROI at current odds

Pros

• + Market strongly favors the home player, reflecting low variance in match outcome
• + If additional intelligence (injury news or line movement) appears, odds could briefly misprice

Cons

• - Current odds leave no positive expected value vs our estimate
• - Analysis is constrained by limited supplied data (no form, H2H, or injury details)

Details

The market prices Jannik Sinner at 1.04 (implied probability 96.15%). Based only on the supplied research (surface: outdoor hard and the quoted prices) we estimate a true win probability for the home player of 92.0%. That translates to an expected return of 0.92 * 1.04 - 1 = -0.0432 (negative), so the current price does not offer value. To be profitable backing Sinner at these odds we would need his true win probability to exceed 1/1.04 = 96.154%, which is materially higher than our conservative 92% estimate. Given the limited information available, the gap between implied and our estimated probability is insufficient to justify a bet.

Key factors

• • Bookmaker price implies 96.15% chance for the favorite (very steep)
• • Surface is outdoor hard — neutral for both players per provided data
• • Only limited research provided, so we use a conservative true-win probability
