Highlights

• • Market-implied away probability: ~3.44%; our conservative estimate: 4.0%
• • Current price (29.03) exceeds the minimum fair price (25.00) for our estimate

Pros

• + Positive expected value at current odds if the true upset chance is ≥4%
• + Large payoff relative to stake for even a small probability of upset

Cons

• - Extremely one-sided market suggests heavy favorite — small absolute chance of success
• - No match-specific data available (surface, injuries, form); high model uncertainty

Details

The market prices Juan Pablo Varillas as an overwhelming favorite (home 1.026, implied ~97.5%) and Carlos Maria Zarate as a very long underdog (away 29.03, implied ~3.44%). We have no external research on surface, form, injuries, or H2H, so we adopt a conservative upset estimate for the away player of 4.0% (0.04). That estimate is modestly above the market-implied away probability of 3.44%, creating positive expected value. At p=0.04 the minimum fair decimal price is 25.00; the current available 29.03 therefore offers value. We flag substantial model and information risk because the market is extremely one-sided and we lack player-specific data.

Key factors

• • Market-implied away probability is ~3.44% (29.03) — we estimate slightly higher at 4.0%
• • No external data on surface, injuries, form or H2H — we use a conservative upset baseline
• • Very large market favorite means small absolute probability differences can create high ROI
