**COL ML +176 | Model Edge: +16.9% | Tier 1** Sean Sullivan enters with a 2.87 FIP and a 0.67 WHIP, translating to a pitcher composite of 64.0 — meaningfully ahead of Javier Assad's 50.71 despite Assad's surface-level 4-1 record. Assad's FIP of 4.09 sits slightly above his 3.99 ERA, suggesting his results have been roughly in line with his underlying profile rather than outperforming it, and Colorado's lineup posts a .745 OPS against right-handed pitching, a 12-point edge over Chicago's .733 OPS against lefties. The model prices Colorado's win probability at 53.1% on the road, while the market is offering +176 — implying only about 36.2% — and that 16.9% gap is where the quantifiable disagreement lives. At that implied probability mismatch, this line warrants a measured position.
