1.9σ gap
wOBA-against (actual)0.302
xwOBA-against (deserved)0.255

Tolle’s wOBA-against sits at 0.302, but the quality of contact underneath says it should be 0.255 — a gap of 0.047, 1.9 standard deviations from the MLB norm over 150 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
