Home plate: John Tumpane
“A steady night's work behind the plate.”
What this shows — how John Tumpane called the 157 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 149 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

Jake Cronenworth vs Justin Martinez - 2-0.20▼3 · 2-1 ball called strike
Manny Machado vs Michael Soroka - 3+0.13▲5 · 1-1 strike called ball· challenged
Pavin Smith vs Randy Vásquez
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
3 pitches went to the robots · 0 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Freddy Fermin — ump said ball, robot ruled ball: upheld.
- 2James McCann — ump said ball, robot ruled ball: upheld.
- 3James McCann — ump said ball, robot ruled ball: upheld.
Our tracked-rulebook zone matched the ABS ruling on 1 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
