PA (Plate Appearances):
Every completed turn at the plate, including walks, hit-by-pitches and sacrifices.
wOBA (Weighted On-Base Average):
An on-base rate that weights each way of reaching base by how many runs it is actually worth.

About Single-Season PIV

PIV (Player Impact Value) combines production quality (wOBA relative to the league average) with quantity (plate appearances): PIV = (wOBA − League Average wOBA) × PA. The single-season leaderboard is restricted to the Modern Era (1901+), since pre-1901 rules make those seasons incomparable. Read the full methodology →
