Regression watch
Running hot. Expect some cooling.
Wetherholt’s wOBA sits at 0.351, but the quality of contact underneath says it should be 0.351 — a gap of 0.000, -0.0 standard deviations from the MLB norm over 421 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
