The heat map answers one question at a glance: where is the market mispricing a player tonight? Every box is a player’s best available price measured against the rest of the market — in cents of value, vig included.

🎓 Wait — this isn’t a pitch-zone heat map? ▾

Correct — and that’s the point. The heat maps you see on baseball sites show where a pitch crosses the plate — a hitter’s hot zones, a pitcher’s tendencies. Useful, free everywhere, and it tells you about the baseball while saying nothing about the price. A hitter crushing low-away sliders is worthless if the line already knows it.

This is a heat map of the betting market itself. Each cell scans every sportsbook on our feed and lights up where the books disagree with each other — one book hanging a price the rest of the market says is wrong. It doesn’t care why the edge exists. It just finds where the money is mispriced right now, in cents, so you shop the right book before you bet.

Almost nobody offers this free, because it requires the full multi-book feed. The pitch-zone kind — The Zone Lab, batter-vs-pitcher zone overlays — is on our build board. When both maps fire on the same player, that’s the pick of the night.

😄 Looking for the standard MLB player heat map? Well… here it is: 🎯 The Zone Lab — in-house now, with the batter-vs-pitcher overlay. Or the raw MLB page:

Opens his official MLB Statcast page — pitch-zone charts, exit velo, the whole classic kit. We’ll bring it in-house when The Zone Lab ships.

Rows are players, columns are markets — strikeouts, total bases, hits and the rest, keyed at the top of each column.
The number in the box is the edge: how many cents better the best book is than the market. Bigger number, hotter box.
The color is the temperature: blue warm → green hot → gold fire → red inferno. Red boxes are where books disagree hardest — the raw material of every lock and middle.
