Unlucky so far. Better days ahead.

0.6σ gap
wOBA (actual)0.270
xwOBA (deserved)0.293

Naylor’s wOBA sits at 0.270, but the quality of contact underneath says it should be 0.293 — a gap of 0.023, 0.6 standard deviations from the MLB norm over 116 PA. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
