Highlights
- • Market overestimates Giulio Zeppieri’s probability relative to normalized win rates
- • Uchiyama’s normalized probability (≈43.9%) requires only ~2.279 decimal to breakeven; current 2.65 offers upside
Pros
- + Positive expected value at current market odds using the provided win-loss data
- + Both players have recent hard-court activity in the supplied research, limiting major surface mismatch concerns
Cons
- - Research lacks head-to-head data, explicit injury/fitness details and comprehensive form context
- - Estimated probability is derived from aggregate win rates and may not capture matchup-specific dynamics
Details
We compare the two players using the provided win-loss records and current market pricing. Uchiyama shows a career match win rate of 26-31 (≈45.6%) while Zeppieri is 28-20 (≈58.3%). Normalizing those rates to estimate a head-to-head probability gives Uchiyama ≈43.9% and Zeppieri ≈56.1%. The market-implied probability at the quoted decimals is ≈37.7% for Uchiyama (1/2.65) and ≈69.4% for Zeppieri (1/1.44). Comparing our estimated Uchiyama true probability (≈43.9%) to the market price for the home side (2.65) produces positive expected value: EV = 0.4389 * 2.65 - 1 ≈ +0.162 (16.2% ROI on a 1-unit stake). We therefore identify value on Uchiyama at the current home price because the market understates his win chance relative to a simple, data-driven normalization of the provided win rates. We note uncertainty due to limited contextual info (surface form, H2H, match fitness), so this is a value play based on the supplied records and current odds.
