June 25, 2026 — MLB Prediction & Betting Pick
Our model leans Seattle Mariners
On balance, more tracked inputs leaned Pittsburgh Pirates (13 edges vs 5 for Seattle Mariners).
Note: the model leans Seattle Mariners even though the simple edge count favors Pittsburgh Pirates.

The edge count treats every metric equally, but the model does not.
