Reynaldo López

data as of June 3, 2026·week 10

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

His ERA sits at 3.31, but the underlying numbers do not support it. The key driver is his BABIP-against of .258, well below the league average of .295. BABIP-against needs around 800 balls in play to be reliable; he has 103, so that gap is luck, not skill. His expected ERA is 4.77, a full 1.46 runs higher than the surface ERA, pointing directly at regression. Limited data: this call rests on a 35-inning sample where the luck story is clear. His strikeout rate (20.5%) and contact suppression (hard-hit and barrel rates) are near league average, so there is no elite skill to fall back on once the BABIP normalizes. Sell high.
