Regression watch
Running hot. Expect some cooling.
Happ’s wOBA sits at 0.349, but the quality of contact underneath says it should be 0.314 — a gap of 0.035, -1.4 standard deviations from the MLB norm over 652 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
