Post-Game Analysis

How our model performed

The Giants defeated the Cubs 18-3.

Our model predicted the Giants would win with 52% confidence -- and they delivered. A close call, but the model's slight lean proved correct.

Looking at the factors our model weighed:

  • Rest Days favored the Giants and was a major factor: Giants rest advantage (1 day rest) over Cubs (back-to-back)
  • Home Field Advantage favored the Cubs and was a notable factor: Base home field advantage applied (no detailed stats available)
  • Injuries was neutral and a contributing factor: Similar injury situations: Cubs (0 out) vs Giants (0 out)

This analysis was generated from our model's pre-game assessment compared against the actual result. Factor accuracy helps improve future predictions.
