-0.4σ gap
wOBA-against (actual)0.332
xwOBA-against (deserved)0.344

Ritchie’s wOBA-against sits at 0.332, but the quality of contact underneath says it should be 0.344 — a gap of 0.012, -0.4 standard deviations from the MLB norm over 61 IP. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
