Running hot. Expect some cooling.

-2.4σ gap
wOBA (actual)0.406
xwOBA (deserved)0.326

Rojas’s wOBA sits at 0.406, but the quality of contact underneath says it should be 0.326 — a gap of 0.080, -2.4 standard deviations from the MLB norm over 175 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
