Final score: SEA 1 — PIT 11
Our projection vs reality
The Diamond Signal’s pre-match projection of 56.1 % in favor of Pittsburgh was substantially validated by the outcome of the game. Pittsburgh’s 11-1 victory over Seattle exceeded the projected margin, though the categorical outcome (PIT victory) aligned with the model’s directional call. The discrepancy between projected and realized scoring differentials (a 10-run differential against a projected margin of roughly 3-4 runs) suggests that our model’s calibration component overestimated Seattle’s resilience in high-leverage situations while underestimating the magnitude of Pittsburgh’s offensive and pitching dominance. The game’s final score did not invalidate the projection’s core thesis—namely, that Pittsburgh possessed a quantifiable advantage—but it did expose limitations in our expected run distribution modeling, particularly in accounting for cumulative offensive pressure against a below-average bullpen in the late innings.
