Home plate: John Tumpane
“Pitchers earned every strike the hard way.”
What this shows — how John Tumpane called the 128 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 118 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

Hyeseong Kim vs Robert Suarez - 2+0.39▼8 · 2-2 strike called ball
Alex Call vs Tyler Kinley - 3+0.10▼1 · 0-1 strike called ball
Kyle Tucker vs Bryce Elder
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.
- 1Alex Call — ump said strike, robot ruled ball: overturned.
- 2Sean Murphy — ump said ball, robot ruled ball: upheld.
- 3Alex Call — ump said strike, robot ruled ball: overturned.
- 4Alex Call — 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.
