Running hot. Expect some cooling.

-0.1σ gap
wOBA-against (actual)0.287
xwOBA-against (deserved)0.289

Mederos’s wOBA-against sits at 0.287, but the quality of contact underneath says it should be 0.289 — a gap of 0.002, -0.1 standard deviations from the MLB norm over 34 IP. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
