“An honest evening's grade: nothing loud, nothing missed by much.”
What this shows — how Ron Kulpa called the 212 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 199 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
- 1-0.69▼1 · 3-2 ball called strike
Francisco Lindor vs Seth Lugo - 2+0.30▼3 · 3-1 strike called ball
Carson Benge vs Seth Lugo - 3+0.30▲4 · 3-1 strike called ball
Isaac Collins vs Kodai Senga
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.
- 1Juan Soto — ump said strike, robot ruled strike: upheld.
- 2Carter Jensen — ump said ball, robot ruled ball: upheld.
- 3Luis Torrens — ump said ball, robot ruled strike: overturned.
- 4Michael Massey — ump said strike, robot ruled ball: overturned.
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.
