Unlucky so far. Better days ahead.

0.2σ gap
wOBA (actual)0.282
xwOBA (deserved)0.286

Pérez’s wOBA sits at 0.282, but the quality of contact underneath says it should be 0.286 — a gap of 0.004, 0.2 standard deviations from the MLB norm over 383 PA. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
