Running hot. Expect some cooling.

-0.0σ gap
wOBA-against (actual)0.282
xwOBA-against (deserved)0.283

Miles’s wOBA-against sits at 0.282, but the quality of contact underneath says it should be 0.283 — a gap of 0.001, -0.0 standard deviations from the MLB norm over 62 IP. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
