SEA @ TEX
Home plate: Alex MacKay
“Pitchers earned every strike the hard way.”
What this shows — how Alex MacKay called the 141 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 129 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+0.28▼2 · 1-2 strike called ball
Danny Jansen vs Logan Gilbert - 2-0.13▲1 · 1-0 ball called strike
Julio Rodríguez vs Jacob deGrom - 3-0.13▼1 · 1-0 ball called strike
Wyatt Langford vs Logan Gilbert
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
2 pitches went to the robots · 1 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Leo Rivas — ump said strike, robot ruled strike: upheld.
- 2Danny Jansen — ump said strike, robot ruled ball: overturned.
Our tracked-rulebook zone matched the ABS ruling on 1 of 2 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
