Regression watch
Unlucky so far. Better days ahead.
Jones’s wOBA sits at 0.270, but the quality of contact underneath says it should be 0.290 — a gap of 0.019, 0.5 standard deviations from the MLB norm over 117 PA. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
