Seattle Mariners vs Houston Astros
May 13, 2026 — MLB Prediction & Betting Pick
Our model leans Houston Astros
On balance, more tracked inputs leaned Seattle Mariners (17 edges vs 4 for Houston Astros).
Note: the model leans Houston Astros even though the simple edge count favors Seattle Mariners. This can happen because the model weighs each input differently — a single large advantage (like a dominant pitching matchup or a significant offensive gap) can outweigh several smaller edges on the other side. The edge count treats every metric equally, but the model does not.
