Unlucky so far. Better days ahead.
Grissom’s wOBA sits at 0.318, but the quality of contact underneath says it should be 0.334 — a gap of 0.016, 0.5 standard deviations from the MLB norm over 211 PA. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
