“The kind of night where the umpire is the least of the story.”
What this shows — how Hunter Wendelstedt called the 150 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 140 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.
