Regression watch
Running hot. Expect some cooling.
Rocchio’s wOBA sits at 0.323, but the quality of contact underneath says it should be 0.294 — a gap of 0.029, -1.1 standard deviations from the MLB norm over 602 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
