Unlucky so far. Better days ahead.

1.2σ gap
wOBA-against (actual)0.320
xwOBA-against (deserved)0.284

Santos’s wOBA-against sits at 0.320, but the quality of contact underneath says it should be 0.284 — a gap of 0.036, 1.2 standard deviations from the MLB norm over 65 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
