At-Bat Logger
The At-Bat Logger records hitting results for each batter. Data from the At-Bat Logger drives batting average, on-base percentage, slugging, and all hitting analytics.
Batter Selection
When a lineup is confirmed the logger automatically shows the current batter based on the batting order. The order advances automatically after each recorded at-bat. Tap Override if you need to log a different batter (for example a pinch hitter not yet in the order).
Without a confirmed lineup select the batter manually from the player selector at the top of the screen.
Logging an At-Bat
- Select the contact type — how the ball was hit (Ground Ball, Line Drive, Fly Ball)
- Select the result — the at-bat outcome
- Tap the spray chart to indicate where the ball was hit
- Optionally toggle Hard Hit or Long AB
- Set the RBI count if runs scored on the play
- The record saves automatically when both contact type and result are selected
Quick-save results (K, BB, HBP) save immediately without requiring a contact type.

| Type | Description |
|---|---|

Base State — Automatic Updates
After each at-bat the app automatically updates the shared base state visible in the Baserunning Logger:
- 1B, 2B, 3B hits — batter is placed on the appropriate base. If that base is occupied a prompt appears asking where the displaced runner went (advance, score, or out).
- HR — all runners on base score automatically and the bases clear. No action needed in the Baserunning Logger.
- Walk / HBP / Error / FC — batter is placed on first base. Occupied-base conflicts prompt for resolution.
- Outs / K — no base change.
The score counter updates automatically when runners score via the displacement prompt or on a home run.
Spray Chart
Tap the zone on the field diagram where the ball was hit. This drives spray chart heat maps in hitting analytics.
Zones include all outfield areas (Shallow LF, Deep LF, Left Center Gap, Center Field, Right Center Gap, Shallow RF, Deep RF) and infield positions (3B, SS, 2B, 1B, Pitcher/Catcher area).
Hard Hit and Long AB Toggles
Hard Hit — ball hit with significant force. Hard hit rate is tracked separately in analytics.
Long AB — at-bat extended to 6 or more pitches. Long AB rate is a component of Quality At-Bat percentage.
RBI
Tap the RBI selector (0–4) before the result saves. RBI count is stored on the log and appears in season totals.
Quick Navigation
The → Baserunning button in the top right navigates directly to the Baserunning Logger — useful after a hit to manage runners already on base before the next batter.
