Michael Wacha

KC·P
data as of June 3, 2026·week 10

Wacha is a sell-high — his ERA is BABIP smoke and mirrors.

His ERA sits at 3.23, nearly a full run below league average, but the number driving it is unreliable. His BABIP-against is .253, 42 points below the league average of .295 — BABIP-against needs around 800 balls in play to stabilize, and he has 208. That gap is luck, not skill. Strip out the noise and his expected ERA is 3.95, 0.72 higher than the ERA, and it has been stepping down across the sample — meaning the underlying skill is not as sharp as the surface. His strikeout rate, walk rate, and contact quality allowed all sit near league average; there is no elite-stuff story to fall back on. The ERA is a mirage that will fade as the BABIP normalizes. Sell high.
