HOU @ ATH
Home plate: Ryan Additon
“The zone shrank when the pitchers needed it most.”
What this shows — how Ryan Additon called the 161 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 149 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

Shea Langeliers vs Peter Lambert - 2+0.30▼7 · 3-1 strike called ball
Brian Serven vs Bryan King - 3+0.28▲6 · 1-2 strike called ball
Lucas Spence vs Scott Blewett
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 · 1 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Jose Altuve — ump said strike, robot ruled strike: upheld.
- 2Brian Serven — ump said ball, robot ruled ball: upheld.
- 3Yainer Diaz — ump said ball, robot ruled ball: upheld.
- 4Brian Serven — 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), not our error.
