Rizzler's bullpen tracking lets coaches chart practice pitching sessions pitch by pitch — logging location, type, and outcome — then compare bullpen performance to in-game results. See whether your pitcher's curveball actually breaks the same way on game day as it does in practice.

Most coaches run bullpen sessions at practice and judge the results by eye. The kid looked good, his fastball was hitting spots, the changeup had decent movement. But how does that translate to a live at-bat with runners on?

Bullpen tracking closes that gap. Chart every pitch in practice the same way you'd chart pitches in a game. Build a pitch-by-pitch record of bullpen sessions. Then compare the data side by side: practice strike percentage versus game strike percentage, practice pitch location versus game pitch location, practice velocity patterns versus game velocity patterns.

For the first time, you have data on what a pitcher does in practice — not just what they do under pressure.

Step 1: Start a bullpen session. Open Rizzler on your phone, select the pitcher, and start charting. Same interface as in-game pitch charting — tap the zone where each pitch lands.

Step 2: Log pitch type and result. For each pitch, record the type (fastball, changeup, curveball, etc.) and the result (strike, ball, swinging strike, foul). At the youth level, most coaches track location and result — velocity is optional if you have a radar gun.

Step 3: Review the session heatmap. After the session, Rizzler generates a heatmap showing where pitches landed. You'll see patterns instantly — is the fastball consistently arm-side? Is the curveball landing in the zone or bouncing in the dirt?

Step 4: Compare to game data. This is where it gets powerful. Rizzler shows practice heatmaps next to game-day heatmaps. If your pitcher's bullpen strike percentage is 72% but their game strike percentage is 54%, you know they're losing command under pressure — and that's a coaching conversation worth having.
