Liberatore is a sell — his skill is below league with no luck excuse.

His expected ERA is 5.23, a full run above the league average of 4.10, and he has faced enough batters for that number to be reliable. His actual ERA is not hiding anything — his BABIP-against is near league average, so there is no bad-luck story inflating the surface. The underlying metrics confirm the problem: he allows hard contact at a 42.6% clip, well above league, and his barrel rate is elevated. His strikeout rate is actually a tick below league average, and his walk rate is slightly above. None of these numbers are propped up by noise. The xERA has been trending up across the sample — the skill is not improving. There is no bounce-back waiting here; this is the level he is at. Sell. 50 K / 4.83 ERA / 1.38 WHIP: a clear drop — no hidden skill to save this streaming-only production.
