Running hot. Expect some cooling.

-0.2σ gap
wOBA (actual)0.281
xwOBA (deserved)0.275

Rogers’s wOBA sits at 0.281, but the quality of contact underneath says it should be 0.275 — a gap of 0.005, -0.2 standard deviations from the MLB norm over 166 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
