Regression watch
Running hot. Expect some cooling.
Seigler’s wOBA sits at 0.328, but the quality of contact underneath says it should be 0.312 — a gap of 0.016, -0.5 standard deviations from the MLB norm over 175 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
