MLB’s approach to the minor leagues is ripe for change in part because of how much data can be collected off the field these days. Independent hitting instructor Doug Latta tells his clients that they “don’t need much space to get better,” as improving via reps, video analysis and ball-tracking tech lessens the need for a player to play in regulation games. Latta worked with Marlon Byrd, Justin Turner and Hunter Pence in various storage-like facilities just before they changed their approach at the plate and improved their performance. Cody Bellinger was already a good major league player but became great this season after he changed his swing in similar modest spaces last winter. While batting cages have existed since Rickey invented them, they’ve never been the feedback machines they are today when outfitted with ball-, bat- and body-tracking tech.
On the pitching side, it’s perhaps even easier to gain skills. Adam Ottavino designed a new cutter last winter in a vacant Manhattan storefront that he outfitted with baseball’s cutting-edge tech. The Los Angeles Dodgers held several low-value minor league pitchers back from minor league games in 2016, giving them something of an extended spring training at their complex to see if they could improve throwing velocity. Dodgers pitchers Corey Copping and Andrew Istler learned how to throw harder and subsequently became trade chips last summer.
