Details
We estimate Guillaume Dalmasso is the clear favorite but we do not see value at the current prices. Dalmasso's career win-rate (27-26) and recent clay exposure give him a meaningful edge vs Leyton Rivera (10-23), so we estimate Dalmasso's true win probability at about 67%. The market price of 1.307 implies ~76.5% probability; at that price the expected return is negative (EV = 0.67 * 1.307 - 1 = -0.124). The away price (3.22) implies ~31.0% and would require Rivera to be ~31.0%+ likely to be profitable; our assessment of Rivera (~33% career average adjusted down for form and record) is below that threshold when considering surface and form, so neither side offers positive expected value. Therefore we recommend no bet.
Key factors
