López is a sell — the skill sits below league and the sample is stable.

His expected ERA is 4.63, more than half a run above the league average of 4.10, and he has faced enough batters for that number to be reliable. This is not a case of a good pitcher dragged down by bad luck — his BABIP-against is not inflating the damage, so there is no correction coming. The contact he allows backs it up: a .330 expected wOBA allowed against a .315 league mark, in a sample past the point where that stabilizes. The strikeout rate is 21.6%, right at league average, and the walk rate is 9.5%, worse than the 8.0% league mark. His expected ERA has been stepping up across the sample, not settling down. There is no luck story to fall back on. Sell. A 4.30 ERA and 1.34 WHIP over 7 K is streaming-only, deep-league fringe — a drop, not a hold.
