BOS @ BAL
Home plate: Dexter Kelley
“The zone leaned, and the ledger noticed.”
What this shows — how Dexter Kelley called the 132 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. 123 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+0.23▲6 · 0-2 strike called ball· challenged ✓
Andruw Monasterio vs Anthony Nunez - 2+0.13▲1 · 1-1 strike called ball· challenged ✓
Roman Anthony vs Kyle Bradish - 3-0.13▼8 · 1-1 ball called strike
Dylan Beavers vs Jovani Morán
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 · 2 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Carlos Narváez — ump said ball, robot ruled strike: overturned.
- 2Leody Taveras — ump said strike, robot ruled strike: upheld.
- 3Adley Rutschman — ump said ball, robot ruled ball: upheld.
- 4Carlos Narváez — ump said ball, robot ruled strike: overturned.
- 5Jahmai Jones — ump said strike, robot ruled strike: upheld.
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.
