Unlucky so far. Better days ahead.

0.1σ gap
wOBA (actual)0.340
xwOBA (deserved)0.343

Tatís’s wOBA sits at 0.340, but the quality of contact underneath says it should be 0.343 — a gap of 0.003, 0.1 standard deviations from the MLB norm over 426 PA. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
