Unlucky so far. Better days ahead.

2.5σ gap
wOBA-against (actual)0.442
xwOBA-against (deserved)0.369

Richardson’s wOBA-against sits at 0.442, but the quality of contact underneath says it should be 0.369 — a gap of 0.073, 2.5 standard deviations from the MLB norm over 61 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
