Home plate: John Tumpane
“The zone had a case of the wanders.”
What this shows — how John Tumpane called the 162 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 147 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
2 pitches went to the robots · 2 overturned (ump overruled) · 0 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Willy Adames — ump said strike, robot ruled ball: overturned.
- 2Ha-Seong Kim — ump said strike, robot ruled ball: overturned.
Our tracked-rulebook zone matched the ABS ruling on 2 of 2 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
