“An honest evening's grade: nothing loud, nothing missed by much.”
What this shows — how Laz Diaz called the 169 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 157 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.
