Regression watch
Unlucky so far. Better days ahead.
Halpin’s wOBA sits at 0.282, but the quality of contact underneath says it should be 0.295 — a gap of 0.013, 0.4 standard deviations from the MLB norm over 201 PA. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
