Sarafina Olivia Hansen vs Pauline Gloeckner

Highlights

• • Normalized home win probability ≈ 45.7%
• • Required fair odds to back home would be ≥ 2.19 (market is 2.02)

Pros

• + Clear, conservative approach: remove vig and avoid overbetting on noisy ITF matches
• + Avoids backing small edges that disappear under high match variance

Cons

• - Lack of match-specific data could conceal a real edge (unknown form/injury/surface advantage)
• - Market may misprice favorites in some books; without data we can't responsibly exploit outliers

Details

We have no external data on form, surface, injuries, or H2H, so we start from the quoted market prices and remove the bookmaker margin. The raw implied probabilities from the decimals (Home 2.02 -> 49.5%, Away 1.699 -> 58.9%) sum to ~108.4% (vig). After normalizing to remove the vig, we estimate the home win probability at ~45.7% and away ~54.3%. Using our conservative true probability for the home player (0.457) and the current home price (2.02) yields a negative expected value (EV ≈ -0.076), so there is no positive value to back at available market prices. Given the high uncertainty typical of ITF-level matches and lack of additional intel, we recommend taking no side.

Key factors

• • Market prices contain ~8.4% bookmaker margin; normalized probabilities used
• • No external info on surface, injuries, form, or H2H — we use conservative market-normalized estimate
• • ITF-level matches carry high variance and limited predictive signal
