Running hot. Expect some cooling.

-1.8σ gap
wOBA-against (actual)0.298
xwOBA-against (deserved)0.345

Rodriguez’s wOBA-against sits at 0.298, but the quality of contact underneath says it should be 0.345 — a gap of 0.047, -1.8 standard deviations from the MLB norm over 114 IP. The results have outrun the underlying process; as the sample grows, expect the numbers to drift back toward the deserved level.
