Unlucky so far. Better days ahead.

2.3σ gap
wOBA-against (actual)0.405
xwOBA-against (deserved)0.330

Jr.’s wOBA-against sits at 0.405, but the quality of contact underneath says it should be 0.330 — a gap of 0.075, 2.3 standard deviations from the MLB norm over 43 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
