Unlucky so far. Better days ahead.

0.5σ gap
wOBA-against (actual)0.374
xwOBA-against (deserved)0.360

Rodriguez’s wOBA-against sits at 0.374, but the quality of contact underneath says it should be 0.360 — a gap of 0.014, 0.5 standard deviations from the MLB norm over 98 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
