wOBA (actual)0.328

Fermín’s wOBA sits at 0.328, but the quality of contact underneath says it should be 0.277 — a gap of 0.051, -1.6 standard deviations from the MLB norm over 191 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
