Running hot. Expect some cooling.

-0.4σ gap
wOBA-against (actual)0.276
xwOBA-against (deserved)0.287

Melton’s wOBA-against sits at 0.276, but the quality of contact underneath says it should be 0.287 — a gap of 0.011, -0.4 standard deviations from the MLB norm over 96 IP. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
