BOS @ DET
Home plate: Jonathan Parra
“Down the middle. Both dugouts had the same zone.”
What this shows — how Jonathan Parra called the 170 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 165 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 · 3 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Spencer Torkelson — ump said strike, robot ruled ball: overturned.
- 2Dillon Dingler — ump said ball, robot ruled strike: overturned.
- 3Dillon Dingler — ump said ball, robot ruled strike: overturned.
- 4Carlos Narváez — ump said ball, robot ruled ball: upheld.
Our tracked-rulebook zone matched the ABS ruling on 4 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
