a place where you can select the baseball game you're watching and see the scouting report heatmaps (most effective pitch locations) for each at bat as they happen
I used to design scouting reports for the pros and it was always really fun to follow along while watching the game
that’s why I’m making @heatzoneapp. every pitcher’s arsenal and hitter’s historical data vs similar pitches are so uniquely their own, that the heatmaps are likely very similar to what the pros are actually studying, based on THE ultimate stat, xwoba
One of the coolest visualizations I've ever seen-- the evolution of the MLB strike zone from 2007 to 2025.
The zone has changed dramatically-- going from vibes to nearly matching the rulebook definition perfectly.
They're remarkably good.

I'm the first fan I made this for and I am loving it, trying to see if others share the same fun I have in following the pitchers' targets and seeing how the AB results often are consistent with the data. Let me know what you think ⚾️
