Regression watch
Running hot. Expect some cooling.
Griffin’s wOBA sits at 0.342, but the quality of contact underneath says it should be 0.304 — a gap of 0.039, -1.3 standard deviations from the MLB norm over 290 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
