Running hot. Expect some cooling.

-3.2σ gap
wOBA (actual)0.346
xwOBA (deserved)0.221

Rojas’s wOBA sits at 0.346, but the quality of contact underneath says it should be 0.221 — a gap of 0.125, -3.2 standard deviations from the MLB norm over 109 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
