Regression watch
Running hot. Expect some cooling.
Donovan’s wOBA sits at 0.438, but the quality of contact underneath says it should be 0.314 — a gap of 0.124, -3.7 standard deviations from the MLB norm over 187 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
