Unlucky so far. Better days ahead.

0.9σ gap
wOBA-against (actual)0.315
xwOBA-against (deserved)0.284

Soto’s wOBA-against sits at 0.315, but the quality of contact underneath says it should be 0.284 — a gap of 0.030, 0.9 standard deviations from the MLB norm over 42 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
