The Little League World Series sets a strict set of parameters: a 42‑inch pitching distance, a maximum of 90 pitches per game, and a mandated 10‑second rest between appearances. These figures are not arbitrary; they emerge from decades of research on youth arm health and competitive equity.
Beyond the numbers lies a philosophy: limit exposure to reduce injury risk, enforce rest to build stamina, and maintain a level playing field so that skill, not sheer volume, determines success. By dissecting these choices, we uncover patterns that extend well past a softball diamond.
