Disappointing 2018 Studs: Altuve, Stanton, & Bellinger
Batter production can roller coaster up-and-down during a season and many times the player’s production eventually stabilizes at an expected level. But sometimes a hitter intentionally or unintentionally changes his plate approach to achieve a new talent level. I’m going to examine three top hitters, Cody Bellinger, Giancarlo Stanton, and Jose Altuve, and why their struggles are caused by changes in approach.
Over my years of research, I’ve found three main items which point to a true talent change, swinging at pitches out of the strike zone, hitting pitches in the strike zone, and groundball rate (verified with launch angle). When one of these items change, the hitter’s production should also change. Luck could still be a factor in the short run but given enough time, there will be a new output level.
