Pitching & run expectancy

Seattle Mariners have won 2 of their last 5 (W-L-W-L-L, most recent first). Boston Red Sox have won 1 of their last 5 (L-L-L-L-W, most recent first).
The last 5 meetings (Seattle Mariners–Boston Red Sox): 4–2, 7–4, 1–3, 8–0, 0–2. On a small sample the head-to-head is context, not a dominant signal — the model's depth carries the probability, not a handful of individual results.
What to watch
The model makes Seattle Mariners the favourite at 60%, but at 40% Boston Red Sox is far from a write-off. The early stages often decide it: whoever sets the tempo first can swing the probabilities quickly. Watch whether the favourite asserts itself early or the game stays open — that is where the model's lean is won or lost.
