Unlucky so far. Better days ahead.

0.2σ gap
wOBA (actual)0.293
xwOBA (deserved)0.300

Vierling’s wOBA sits at 0.293, but the quality of contact underneath says it should be 0.300 — a gap of 0.007, 0.2 standard deviations from the MLB norm over 281 PA. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
