Seth Keshel is a consultant to a number of MLB hitters. He recently got his first look at SeamTrak and had this to say:
Warren Spahn said “hitting is timing, pitching is upsetting timing”. Nearly every hitting flaw or negative tendency can be traced to the inability of a hitter to consistently recognize various pitch types in time to adjust his approach.
SeamTrak provides outstanding training for hitters looking to gain a competitive edge in a world where only 250 milliseconds exist to make a decision to swing against a hittable fastball or to hold back against a slider that is going to miss down and away.
I highly recommend this application for any hitter’s training library, whether that hitter is an established Major League veteran or an eight year old seeing live pitching for the first time.
