Regression watch
Running hot. Expect some cooling.
Happ’s wOBA sits at 0.364, but the quality of contact underneath says it should be 0.319 — a gap of 0.045, -1.6 standard deviations from the MLB norm over 416 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
