Unlucky so far. Better days ahead.

0.2σ gap
wOBA-against (actual)0.314
xwOBA-against (deserved)0.307

Hall’s wOBA-against sits at 0.314, but the quality of contact underneath says it should be 0.307 — a gap of 0.007, 0.2 standard deviations from the MLB norm over 35 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
