Shown for reference only. Our side model measures at a coin flip (Brier 0.253 vs 0.250), so a gap here is not an edge — it is three independent guesses, and the two market numbers are the better-informed ones. Before first pitch the first column is the league-average home win rate, not a projection for this matchup — the per-game simulation runs once the game starts.

Velocity & spin from the MLB Stats API live feed. The fatigue read compares each pitcher's live fastball velocity to their fresh baseline and our fatigue-curve model (−0.61 mph / 100 pitches). Win probability is from our own base-out/inning/score table built on 2024–25 games.
