Unlucky so far. Better days ahead.
Vierling’s wOBA sits at 0.296, but the quality of contact underneath says it should be 0.302 — a gap of 0.006, 0.2 standard deviations from the MLB norm over 285 PA. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
