I think some of his struggles probably have to do with his different release point this season (much higher vertically) creating a easier angle for hitters to pick up his pitches, and also possibly contributing to his frequent loss of command and control. While it sounds like it should be an easy fix, I assume it’s probably a little difficult in the middle of a season to just alter your release point and maintain it consistently with all of your pitches. The Brewers have seemingly been at the leading edge of many recent pitching trends and advances including the role arm angles play in generating deception, movement, and seam shifted wake. At the very least I do wonder if the Brewers pitch data for Hader this season was setting off alarm bells to the point they believed he’d continue to struggle for the remainder of the season.
