Unlucky so far. Better days ahead.

0.2σ gap
wOBA-against (actual)0.402
xwOBA-against (deserved)0.394

Rodriguez’s wOBA-against sits at 0.402, but the quality of contact underneath says it should be 0.394 — a gap of 0.008, 0.2 standard deviations from the MLB norm over 31 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
