Running hot. Expect some cooling.

-0.1σ gap
wOBA-against (actual)0.269
xwOBA-against (deserved)0.273

Waguespack’s wOBA-against sits at 0.269, but the quality of contact underneath says it should be 0.273 — a gap of 0.003, -0.1 standard deviations from the MLB norm over 48 IP. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
