About PIV

PIV (Player Impact Value) measures a hitter's total offensive contribution by combining production quality (wOBA relative to the league average) with quantity (plate appearances): PIV = (wOBA − League Average wOBA) × PA. The best players sustain elite performance over many plate appearances, so PIV rewards both rate and durability.
