Regression watch
Running hot. Expect some cooling.
Jarvis’s wOBA sits at 0.284, but the quality of contact underneath says it should be 0.268 — a gap of 0.015, -0.4 standard deviations from the MLB norm over 126 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
