Each player’s Wins Above Replacement (WAR) is projected through his first six MLB seasons. This is mostly due to MLB’s arcane free agency system granting teams 6 years of player control, but also for some consistency with KATOH, the only other public Minor League projection system I’m familiar with. Minimum 100 plate appearances or total batters faced.
