About PitchGuessr
PitchGuessr is a companion app for MLB The ShowDiamond Dynasty that turns your opponent’s pitching into a readable pattern. As you play, it logs every pitch by zone and builds a live 25-zone heatmap — the spots they keep attacking light up, the ones they avoid fade — so you can see their tendencies forming in real time instead of trying to hold them in your head.
Across games it remembers each opponent, so the second time you face someone you already have their book. It tracks sequences too: what they throw after a first-pitch strike versus when they fall behind 2-0. The payoff is simple — instead of guessing pitch to pitch, you sit on the zone the data says is coming. It’s built for fast, low-distraction input during online ranked play: open it before a game and log as you go.
