Running hot. Expect some cooling.

-0.4σ gap
wOBA-against (actual)0.282
xwOBA-against (deserved)0.295

Faucher’s wOBA-against sits at 0.282, but the quality of contact underneath says it should be 0.295 — a gap of 0.013, -0.4 standard deviations from the MLB norm over 70 IP. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
