Regression watch
Running hot. Expect some cooling.
Collins’s wOBA sits at 0.330, but the quality of contact underneath says it should be 0.310 — a gap of 0.019, -0.7 standard deviations from the MLB norm over 332 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
