Regression watch
Running hot. Expect some cooling.
Perdomo’s wOBA sits at 0.355, but the quality of contact underneath says it should be 0.329 — a gap of 0.026, -1.0 standard deviations from the MLB norm over 601 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
