The ML model identifies a 5.5% edge on Ostapenko, driven largely by `hard_elo_diff` which favors her general rating. However, this metric undervalues Maria's elite grass specialization (Surface ELO 1804). Crucially, the Market Trend signal reveals the market is 'chasing' Ostapenko's recent form (+51 drift vs +23 results), implying her odds of 1.87 are shorter than justified. While Maria's heavy fatigue (7 matches in 14 days at age 38) makes her a risky underdog, the favorite offers no value. We recommend passing on this line.
