Regression watch
Running hot. Expect some cooling.
Hernandez’s wOBA sits at 0.350, but the quality of contact underneath says it should be 0.344 — a gap of 0.005, -0.2 standard deviations from the MLB norm over 506 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
