I mean he kinda has made adjustments, his peripherals have improved this year; 3% increase in BB rate and 8% decrease in K rate and even with the eye test he appears to be having more consistent/patient approaches. He also has a .200 BABIP. So he's basically made all the correct adjustments approach wise to become a competent major league hitter he just hasn't had the change result to hitting for average/power which may be part luck and may still be part of developing by doing more with balls that are in the zone.
