Details

We compare market-implied probabilities to our estimated win chances. The market prices Julia Riera at 1.741 (implied 57.5%) and Vitalia Diatchenko at 2.14 (implied 46.7%). Given the Research (nearly identical career records, mixed clay/hard history, and no injury or H2H edge), we assign a slight edge to the home player but not enough to justify a bet: estimated true probability for Riera ~54% (Diatchenko ~46%). That produces a minimum fair decimal price for Riera of ~1.852 and for Diatchenko of ~2.174. The current market prices are either too short (Riera 1.741 < 1.852) or not long enough (Diatchenko 2.14 < 2.174) to produce positive expected value. Therefore we do not recommend a side at the quoted prices.

Key factors

• • Both players show nearly identical career records and mixed surface experience
• • Market favours the home player but implied price is shorter than our fair estimate
• • No clear injury, form, or H2H advantage evident in the provided Research
