Regression watch
Unlucky so far. Better days ahead.
Kepler’s wOBA sits at 0.252, but the quality of contact underneath says it should be 0.270 — a gap of 0.017, 0.5 standard deviations from the MLB norm over 145 PA. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
