Running hot. Expect some cooling.

-1.1σ gap
wOBA-against (actual)0.297
xwOBA-against (deserved)0.324

Rodriguez’s wOBA-against sits at 0.297, but the quality of contact underneath says it should be 0.324 — a gap of 0.027, -1.1 standard deviations from the MLB norm over 162 IP. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
