Highlights

• • Home underdog needed to win >35.09% to be profitable; we estimate 37.0%
• • Edge is small but positive (≈5.5% ROI per unit) under conservative assumptions

Pros

• + Price (2.85) exceeds our conservative fair-value threshold (2.703)
• + Underdog in tennis commonly retains upset probability that markets can underprice

Cons

• - No match-specific data available (form, surface, H2H, injuries) increases risk
• - Edge is small — vulnerable to slight errors in our probability estimate

Details

We note the market heavily favors the away player at 1.38 (implied ~72.5%) while the home underdog is available at 2.85 (implied ~35.1%). With no external form, surface or injury data available, we apply conservative assumptions: in many neutral-matchup situations the favorite's true win probability is lower than the market-implied 72% and the underdog typically retains meaningful upset equity. We estimate the true probability for the home player at 37.0%, which is modestly above the break-even threshold (1/2.85 ≈ 35.09%), producing a small positive edge. Given the absence of specific disqualifying information (injury, extreme surface mismatch, or dominant head-to-head), the 2.85 price on the home side represents value under our conservative model. We flag substantial uncertainty due to lack of match-specific data, so the edge is small and should be treated as speculative.

Key factors

• • Current market odds: home 2.85 (implied 35.09%), away 1.38 (implied 72.46%)
• • Conservative assumed true probability for home of 37.0% surpasses break-even threshold
• • No match-specific info (surface, injuries, recent form, H2H) — increases uncertainty
