Highlights

• • Current market odds imply a heavy favourite; small errors in probability estimate matter greatly here
• • At our estimate (6%), the away price 10.5 yields EV = -0.37 per unit — not profitable

Pros

• + Market offers a long-shot price on the away player (10.5) which would be attractive if we had evidence of higher upset potential
• + Clear arithmetic: required break-even odds and current odds are straightforward to compare

Cons

• - No substantive match-specific information available to justify a higher true probability for the underdog
• - High variance and small margins mean the market's extreme favourite price is unlikely to be beaten by modest model edge

Details

We find no value at the posted prices. The market prices imply a 96.15% chance for Pauline Gloeckner (1/1.04) and a 9.52% chance for Sosanne Malak (1/10.5). With no additional data available (surface, recent form, injuries, H2H) we adopt a conservative estimate that the underdog Sosanne Malak has about a 6.0% true win probability (we therefore attribute ~94.0% to Gloeckner). At 6.0% true probability the fair decimal price is 16.667; the current 10.5 line produces a negative expected value: EV = 0.06 * 10.5 - 1 = -0.37 (loss of 0.37 units per 1 unit staked). For the heavy favourite to offer positive EV at the current 1.04 price we would need to believe her win chance exceeds 96.15%, which is implausible given the inherent variance and lack of confirmatory information. Therefore we decline to recommend a side.

Key factors

• • Market-implied probabilities: home 96.15%, away 9.52% (vig-adjusted overlap due to rounding)
• • No independent data on surface, form, injuries or H2H to justify materially higher true probability for the underdog
• • Underdog would need >9.52% true win chance to break even at 10.5; our conservative estimate is lower (6%), requiring ~16.67 to be profitable
