September 19, 2025 — MLB Prediction & Betting Pick
Our model leans Arizona Diamondbacks
On balance, more tracked inputs leaned Philadelphia Phillies (13 edges vs 9 for Arizona Diamondbacks).
Note: the model leans Arizona Diamondbacks even though the simple edge count favors Philadelphia Phillies.

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