It is becoming increasingly accepted that a pitcher’s BABIP is largely based on luck. Has a similar study been done with slugging average of balls in play? I suspect that SABIP is somewhat in the pitcher’s hands but I’m interested in seeing some stats.
Someone MAY have done such a study, but for all practical purposes, wouldn’t the number of home runs yielded tell us if a pitcher regularly tosses up meatballs that can be hit a mile? Stat heads DO put a lot of emphasis on home runs yielded, which is about as instructive a stat as slugging percentage, and requires less effort to figure out.
