Wheeler is a sell-high — his ERA is built on BABIP luck.

He is striking out 30.4% of batters and his expected wOBA allowed sits at .254, well below the league average of .315. Those are real skills backed by stable samples. The problem is that his actual ERA of 2.13 is even better than his xERA of 2.63, and the gap comes from a BABIP-against of .239 — 56 points below league average. BABIP-against needs around 800 balls in play to be reliable, and he has 223. That suppressed number is pure noise, and when it normalizes, the ERA will climb toward the xERA. His fastball velocity, chase rate, and whiff rate all support an elite pitcher, but not a 2.13 ERA. The market is pricing the surface. Sell high. 48 K and a 2.63 ERA projection make him a trade-now asset before BABIP regression arrives.
