Details

The market prices Benjamin O'connell at 1.165 (implied win probability ≈ 85.8%). Cade Birrell's available profile shows only two career matches (0-2), both losses, indicating minimal match experience and poor form. Given Birrell's lack of wins and small sample size, we assess O'connell's true win probability materially above the market-implied 85.8%. We estimate O'connell's true win probability at 90.0%, which produces positive expected value at the current price: EV = 0.90 * 1.165 - 1 = +0.0485 (≈ +4.85% ROI). The market margin is small but present; the large favorite price is widely available and offers value versus our conservative estimate because Birrell's recorded results offer little reason to expect an upset.
