Regression watch
Running hot. Expect some cooling.
Jones’s wOBA sits at 0.340, but the quality of contact underneath says it should be 0.331 — a gap of 0.010, -0.3 standard deviations from the MLB norm over 191 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
