wOBA (actual)0.345
xwOBA (deserved)0.305

Yastrzemski’s wOBA sits at 0.345, but the quality of contact underneath says it should be 0.305 — a gap of 0.040, -1.3 standard deviations from the MLB norm over 273 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
