Unlucky so far. Better days ahead.

2.4σ gap
wOBA-against (actual)0.354
xwOBA-against (deserved)0.280

Anderson’s wOBA-against sits at 0.354, but the quality of contact underneath says it should be 0.280 — a gap of 0.074, 2.4 standard deviations from the MLB norm over 58 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
