Running hot. Expect some cooling.

-0.5σ gap
wOBA-against (actual)0.194
xwOBA-against (deserved)0.211

Lee’s wOBA-against sits at 0.194, but the quality of contact underneath says it should be 0.211 — a gap of 0.017, -0.5 standard deviations from the MLB norm over 44 IP. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
