ATH @ HOU
Home plate: Ryan Wills
“The kind of night where the umpire is the least of the story.”
What this shows — how Ryan Wills called the 168 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 161 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

Run impact from the count run-value table: a missed strike three is worth far more than one on 3-0.
