Regression watch
Running hot. Expect some cooling.
Castro’s wOBA sits at 0.347, but the quality of contact underneath says it should be 0.294 — a gap of 0.053, -1.9 standard deviations from the MLB norm over 341 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
