Running hot. Expect some cooling.

-1.2σ gap
wOBA (actual)0.350
xwOBA (deserved)0.309

Marte’s wOBA sits at 0.350, but the quality of contact underneath says it should be 0.309 — a gap of 0.042, -1.2 standard deviations from the MLB norm over 142 PA. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
