Running hot. Expect some cooling.

-1.1σ gap
wOBA (actual)0.359
xwOBA (deserved)0.319

Mateo’s wOBA sits at 0.359, but the quality of contact underneath says it should be 0.319 — a gap of 0.040, -1.1 standard deviations from the MLB norm over 151 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
