Regression watch
Running hot. Expect some cooling.
Herrera’s wOBA sits at 0.384, but the quality of contact underneath says it should be 0.363 — a gap of 0.022, -0.8 standard deviations from the MLB norm over 313 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
