Running hot. Expect some cooling.

-2.6σ gap
wOBA (actual)0.453
xwOBA (deserved)0.352

Mateo’s wOBA sits at 0.453, but the quality of contact underneath says it should be 0.352 — a gap of 0.101, -2.6 standard deviations from the MLB norm over 114 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
