Source: statcast_milb (Baseball Savant, minors). The minor feed is a season aggregate that mixes levels, so absolute xwOBA runs high and isn’t comparable to MLB — read the percentile next to each rate, not the raw number. Percentiles rank within the pool. Gap = actual wOBA − expected xwOBA, centered on the pool median; a hitter well below the median with strong contact is buying low.
