Unlucky so far. Better days ahead.
Acuña’s wOBA sits at 0.374, but the quality of contact underneath says it should be 0.378 — a gap of 0.004, 0.1 standard deviations from the MLB norm over 244 PA. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
