Home plate: Clint Vondrak
“The zone kept its promises.”
What this shows — how Clint Vondrak called the 170 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. 157 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▼8 · 3-2 strike called ball
Jake Mangum vs Ryan Walker - 2+0.39▲4 · 2-2 strike called ball· challenged ✓
Turner Hill vs Khristian Curtis - 3+0.30▼3 · 3-1 strike called ball
Oneil Cruz vs Blade Tidwell
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 · 3 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Jared Triolo — ump said strike, robot ruled ball: overturned.
- 2Andrew Knizner — ump said ball, robot ruled ball: upheld.
- 3Rafael Flores Jr. — ump said ball, robot ruled strike: overturned.
- 4Rafael Flores Jr. — ump said ball, robot ruled strike: overturned.
Our tracked-rulebook zone matched the ABS ruling on 3 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone). Where the two disagree, the umpire is graded on the ABS ruling.
