Gómez is a sell-high — his ERA is running on borrowed BABIP.

His ERA reads 3.5, but the expected ERA tells the truth at 5.18 — that is a run and a half gap, and the difference is his BABIP-against. It sits at .255 against a league average of .295, and BABIP-against needs around 800 balls in play to be reliable. He has 173. That gap is luck, not skill. His xERA has stepped up across the sample, and his strikeout rate is 21.4%, just below league, with a walk rate of 12.4% — well above the 8% average. Nothing under the hood supports the surface. The talent is not pulling the line down; the luck is holding it up. Sell high. A 4.66 ERA and 1.42 WHIP rest-of-season is a drop, not a hold — sell the window before regression lands.
