STL @ DET
Home plate: Nate Tomlinson
“A workmanlike night — nothing to frame, nothing to fix.”
What this shows — how Nate Tomlinson called the 186 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 176 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

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 · 4 overturned (ump overruled) · 0 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Iván Herrera — ump said strike, robot ruled ball: overturned.
- 2Dillon Dingler — ump said strike, robot ruled ball: overturned.
- 3Pedro Pagés — ump said ball, robot ruled strike: overturned.
- 4Kevin McGonigle — ump said strike, robot ruled ball: overturned.
Our tracked-rulebook zone matched the ABS ruling on 2 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
