wOBA Weights

Year-by-year constants used for Weighted On-Base Average

wOBA Calculation Formula

wOBA = (wBB×BB + wHBP×HBP + w1B×1B + w2B×2B + w3B×3B + wHR×HR) / (AB + BB – IBB + SF + HBP)

wOBA Scale is used to scale the raw wOBA calculation to match the league OBP, making it easier to interpret (like OBP).
