I think it's a trick from K-Zone. Every year ESPN's K-Zone gets flak for stuff like this. Because K-Zone makes it look low, we automatically believe it with our eyes. But here is the Statcast track of the Bogaerts PA.
That's a strike according to Savant. Similar things were happening early in this series when PCA was swinging up and inside. K-zone said he was chasing, Savant had him swinging at high strikes in the zone.
It's always tough to figure out which system is the best as the zone is not something that lives on a two dimensional plane, but something that exists in three. Yet K-Zone and Savant both depict is as flat. As long as a pitch clips the zone in that three dimensional plane, it's a strike according to the rules. What makes that hard is showing it throw a flat, 2-d panel and how it may or may not clip that zone.
I always tend to lean towards Savant. I use K-zone from a viewing standpoint and then allow Savant to either confirm or refute the K-Zone call (I am that dork who has a 3-screen split when watching games which includes a Savant screen. This is a judgement free zone) This is getting first party data from MLB's system direct, Hawk Eye. Hawk Eye will be used by the ABS system next year. Just feels the most prudent everything considered.
