Regression watch
Running hot. Expect some cooling.
Collins’s wOBA sits at 0.303, but the quality of contact underneath says it should be 0.295 — a gap of 0.007, -0.3 standard deviations from the MLB norm over 532 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
