Unlucky so far. Better days ahead.

0.6σ gap
wOBA (actual)0.286
xwOBA (deserved)0.304

Vierling’s wOBA sits at 0.286, but the quality of contact underneath says it should be 0.304 — a gap of 0.017, 0.6 standard deviations from the MLB norm over 310 PA. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
