“An honest evening's grade: nothing loud, nothing missed by much.”
What this shows — how Erich Bacchus called the 119 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 111 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+0.23▲9 · 0-2 strike called ball
Vinnie Pasquantino vs Jacob Waguespack - 2+0.13▼1 · 1-1 strike called ball
Gleyber Torres vs Michael Wacha - 3-0.09▲5 · 0-0 ball called strike
Andrew Velazquez vs Casey Mize
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
1 pitch went to the robots · 0 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Carter Jensen — ump said ball, robot ruled ball: upheld.
Our tracked-rulebook zone matched the ABS ruling on 0 of 1 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
