1.0σ gap
wOBA-against (actual)0.344
xwOBA-against (deserved)0.319

Martinez’s wOBA-against sits at 0.344, but the quality of contact underneath says it should be 0.319 — a gap of 0.024, 1.0 standard deviations from the MLB norm over 159 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
