Regression watch
Running hot. Expect some cooling.
Perdomo’s wOBA sits at 0.361, but the quality of contact underneath says it should be 0.333 — a gap of 0.028, -1.2 standard deviations from the MLB norm over 695 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
