Running hot. Expect some cooling.

-0.8σ gap
wOBA (actual)0.315
xwOBA (deserved)0.287

Marte’s wOBA sits at 0.315, but the quality of contact underneath says it should be 0.287 — a gap of 0.028, -0.8 standard deviations from the MLB norm over 185 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
