Regression watch
Running hot. Expect some cooling.
Massey’s wOBA sits at 0.318, but the quality of contact underneath says it should be 0.307 — a gap of 0.011, -0.4 standard deviations from the MLB norm over 246 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
