Unlucky so far. Better days ahead.

2.7σ gap
wOBA-against (actual)0.433
xwOBA-against (deserved)0.345

López’s wOBA-against sits at 0.433, but the quality of contact underneath says it should be 0.345 — a gap of 0.088, 2.7 standard deviations from the MLB norm over 45 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
