Details

We see a large market skew toward Sada Nahimana (market-implied ~85.4%) despite both players having essentially identical recorded form (10-22) and similar surface experience on clay and hard. There is no clear injury or form edge in the research that justifies such a heavy favorite. We conservatively estimate Diana-Ioana Simionescu's true chance at 42% based on parity in recent results, potential home/venue familiarity, and the absence of decisive recent wins for Nahimana. At that probability the break-even decimal odds are ~2.381, while the available market price for Simionescu is 4.37 — creating meaningful value. Using the quoted price (4.37) gives EV = 0.42 * 4.37 - 1 = 0.835 (83.5% ROI on a 1-unit stake), so we recommend backing the home underdog because the market appears to overprice the away player.

Key factors

• • Both players show near-identical career records (10-22) and similar surface experience
• • Market heavily favors the away player (implied ~85%) with no clear justification in the provided research
• • Home/venue and parity considerations make the underdog likelier than market implies
