Evidence-Based Assessment
Colorado Rockies model win probability is 44.0% versus a 40.9% no-vig market baseline (+3.1 percentage points). The baseline score is Arizona Diamondbacks 5.9, Colorado Rockies 5.5 (11.4 total), a +0.4 difference from 11.
The baseline blends each offense’s runs per game with the opposing staff’s runs allowed per game, then applies a limited probable-starter ERA adjustment, home-field adjustment, and a disclosed venue adjustment. It is a transparent comparison tool, not a fitted guarantee.
