STL @ LAA
Home plate: Dan Bellino
“A workmanlike night — nothing to frame, nothing to fix.”
What this shows — how Dan Bellino called the 141 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 134 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.
The zone, as he called it
The calls that moved the game
- 1-0.30▲7 · 3-1 ball called strike
Masyn Winn vs Samy Natera Jr. - 2+0.10▼1 · 0-1 strike called ball
Nolan Schanuel vs Hunter Dobbins - 3+0.10▼7 · 0-1 strike called ball
Oswald Peraza vs Luis Gastelum
Run impact from the count run-value table: a missed strike three is worth far more than one on 3-0.
ABS — the Automated Ball-Strike System
4 pitches went to the robots · 2 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Tyler Heineman — ump said strike, robot ruled ball: overturned.
- 2Masyn Winn — ump said ball, robot ruled strike: overturned.
- 3Tyler Heineman — ump said ball, robot ruled ball: upheld.
- 4Iván Herrera — ump said strike, robot ruled strike: upheld.
Our tracked-rulebook zone matched the ABS ruling on 3 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
