STL @ AZ
Home plate: Tyler Jones
“A workmanlike night — nothing to frame, nothing to fix.”
What this shows — how Tyler Jones called the 201 pitches that were taken (no swing), graded against the tracked rulebook strike zone, or, on a pitch the ABS (Automated Ball-Strike System) reviewed on a challenge, against its ruling. 191 were right. Below, only the misses are plotted, alongside every challenged pitch.
The zone, as he called it
* Graded on the ABS ruling. ABS measures its own zone, set by the batter’s height and taken at the middle of the plate, and our tracking puts this pitch on the other side of the line.
The calls that moved the game
- 1+0.69▲4 · 3-2 strike called ball· challenged ✓
JJ Wetherholt vs Drey Jameson - 2+0.23▼9 · 0-2 strike called ball
Jorge Barrosa vs Luis Gastelum - 3-0.13▲1 · 1-1 ball called strike
JJ Wetherholt vs Eduardo Rodriguez
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
5 pitches went to the robots · 3 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Alec Burleson — ump said strike, robot ruled strike: upheld.
- 2Gabriel Moreno — ump said ball, robot ruled strike: overturned.
- 3Gabriel Moreno — ump said ball, robot ruled strike: overturned.
- 4Iván Herrera — ump said ball, robot ruled ball: upheld.
- 5Nolan Arenado — ump said strike, robot ruled ball: overturned.
Our tracked-rulebook zone matched the ABS ruling on 4 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone). Where the two disagree, the umpire is graded on the ABS ruling.
