The National Federation of State High School Associations on Tuesday said that pitching restriction policies in high school baseball will be based on a pitch count rather than an innings count.
So instead of 10 innings over three calendar days, as the rule has been, each state will determine its own maximum pitch count. Phil Gardner, the assistant IHSAA commissioner who oversees baseball, told IndyStar that the specific policies have not yet been determined, but "will be in place for Indiana in the very near future."
The argument for change comes, in part, from the thinking that a four-pitch inning shouldn't carry the same value as a 24-pitch inning since the two innings put a significantly different amount of stress on an arm.
