**COL ML +176 | Model Edge: +16.9% | Confidence Tier 1** Sean Sullivan carries a 64.0 composite score into this start, backed by a 2.87 FIP and a spartan 0.67 WHIP in his early work — metrics that suggest the surface-level 0-0 record undersells his actual effectiveness. Assad counters at a 50.71 composite, with his ERA (3.99) and FIP (4.09) running in close, unflattering agreement, and his 1.02 WHIP indicating hitters are making consistent contact. Colorado's lineup posts a .746 OPS against right-handed pitching, a meaningful gap over Chicago's .731 OPS against lefties, giving Sullivan a situational edge in the handedness matchup. The market has Colorado priced as a significant underdog, but our model puts their win probability at 53.1% — a 16.9% disagreement with implied odds that represents real quantifiable value at +176.
