Running hot. Expect some cooling.

-1.6σ gap
wOBA-against (actual)0.274
xwOBA-against (deserved)0.320

Wrobleski’s wOBA-against sits at 0.274, but the quality of contact underneath says it should be 0.320 — a gap of 0.046, -1.6 standard deviations from the MLB norm over 77 IP. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
