Regression watch
Running hot. Expect some cooling.
Hernaiz’s wOBA sits at 0.310, but the quality of contact underneath says it should be 0.262 — a gap of 0.048, -1.4 standard deviations from the MLB norm over 168 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
