Regression watch
Unlucky so far. Better days ahead.
Hernandez’s wOBA sits at 0.358, but the quality of contact underneath says it should be 0.358 — a gap of 0.000, 0.0 standard deviations from the MLB norm over 151 PA. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
