Unlucky so far. Better days ahead.

2.0σ gap
wOBA-against (actual)0.378
xwOBA-against (deserved)0.316

Mahle’s wOBA-against sits at 0.378, but the quality of contact underneath says it should be 0.316 — a gap of 0.062, 2.0 standard deviations from the MLB norm over 59 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
