It's kinda funny how velo for pitchers in Spring Training is pretty widely accepted as an important precursor and yet since we don't have access to ST exit velo, it's assumed we can glean nothing from hitter performance. All we're doing is looking at the early performance of a hitter who showed elite exit velo last year and has the tools to be a fantasy relevant. Nobody is pumping up a one-dimensional AAAA DH, we're actually talking about a player who is locked into a starting role for the first time and has been talked about substantially by the analytics community this offseason.
