Regression watch
Running hot. Expect some cooling.
Ruiz’s wOBA sits at 0.346, but the quality of contact underneath says it should be 0.288 — a gap of 0.058, -2.1 standard deviations from the MLB norm over 369 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
