What the panel is really saying

The widest slowpitch disagreement so far — and it stays on the page. Bat Digest scores the Mercy 9.3 and calls it endloaded; the National Pastime Museum scores it 8.1 and calls it balanced. Same bat, two honest readings: one rewards raw performance, the other weights durability at 20% and prices the whole package. Read both before you buy.

Players' Score — rated by players, not reviewers

Collecting the first ratings. The Players' Score is the community score: people who own this bat rating it themselves. It publishes only once this bat reaches 10 email-verified ratings — and it is always shown beside the Panel Score, never blended into it. The reviewers' verdict and the players' verdict — side by side, never mixed.

One rating per email per bat, tallied in checked batches — stuffing gets caught before anything publishes. Your email is never displayed. Durability is the category players know best and reviewers test least: if your bat cracked, say so.
