Regression watch
Unlucky so far. Better days ahead.
Wetherholt’s wOBA sits at 0.336, but the quality of contact underneath says it should be 0.352 — a gap of 0.016, 0.6 standard deviations from the MLB norm over 600 PA. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
