Juan Mejia
Mejia is a hold — the ERA overstates it, the skill doesn't rescue him.
A 5.27 ERA looks like a disaster, but the number doing the damage — a .351 BABIP-against, 56 points above league — is the one stat here you can't trust yet. He has 214 balls in play against a threshold of 800, so that gap is luck, not evidence, and the ERA is worse than what he has pitched. The problem is what sits underneath: his expected ERA is 4.73, .63 above the league average of 4.10, on 323 batters faced. That is past the reliable mark, so this is the level, not an unlucky stretch. He strikes out 20.4% of batters and walks 12.4%, and the walk rate is the real drag. The panic is misplaced and the upgrade isn't there either. Hold. The 4.37 ERA and 1.50 WHIP project as waiver fringe — 0 K, 0 SV means zero strikeout or save upside, so a drop is defensible.
