Our projection vs reality
Diamond Signal’s projection favored the San Francisco Giants (51.2%) over the Chicago Cubs (48.8%) in a matchup that ultimately saw the visiting Cubs secure a 5-1 victory. The model’s median outcome aligned with a Giants win, though the realized result fell outside the projected outcome space. The Cubs’ offensive execution, particularly against starter Landen Roupp, and San Francisco’s inability to counter Javier Assad’s performance contributed to the divergence between expectation and outcome. While the projection did not explicitly account for the Cubs’ 5-run output (which exceeded the model’s anticipated run distribution), the win probability shift toward Chicago was consistent with the Cubs’ superior offensive metrics in the game’s context. The result does not invalidate the projection’s calibration but highlights the inherent variability in baseball outcomes, even when statistical models account for multiple contextual factors.
