Highlights

• • Implied away probability 14.8% vs our estimate 48%
• • EV on away at current odds: +2.24 (224% ROI per 1 unit by our model)

Pros

• + Large margin between market-implied and our estimated true probability
• + Both players’ profiles and recent form do not justify the heavy favorite, supporting the case for underpriced away odds

Cons

• - Limited data depth: no head-to-head, little granular match-level detail, and identical superficial profiles increase uncertainty
• - If bookmakers have unobserved information (injury, late withdrawal, surface-specific edge), the apparent value could evaporate

Details

We find a clear pricing inefficiency. Both players have nearly identical profiles (31 matches, 10-21 record, play clay and hard, similar recent results) so the market-implied split (home 90.9% at 1.10 vs away 14.8% at 6.75) is not supported by the on-paper evidence. Treating the matchup as effectively even-to-close-to-even (we conservatively estimate the away player’s true win probability at 48%), the away line at 6.75 offers large positive expected value. Implied probability at 6.75 is 14.81% (1/6.75). Our estimated true probability of 48% is many times higher than the market-implied 14.8%, producing EV = 0.48*6.75 - 1 = +2.24 (224% ROI for a 1-unit stake). The home price at 1.10 implies ~90.9% and would require a true probability >90.9% to be +EV, which is unsupported by available form, surface history, or head-to-head data. Therefore we recommend backing the away player only because the current price offers meaningful value.

Key factors

• • Both players show nearly identical career records and recent form (10-21 across 31 matches)
• • Market is heavily skewed to the home player (1.10) without supporting evidence from profiles or form
• • Surface experience and recent results do not justify a >90% chance for the home side, so the away line (6.75) is substantially underpriced
