Unlucky so far. Better days ahead.

0.7σ gap
wOBA-against (actual)0.329
xwOBA-against (deserved)0.307

Ginn’s wOBA-against sits at 0.329, but the quality of contact underneath says it should be 0.307 — a gap of 0.022, 0.7 standard deviations from the MLB norm over 73 IP. The results have been worse than the process deserves; as the sample grows, expect the numbers to climb back toward the underlying level.
