Domínguez is a sell-high — his ERA is BABIP noise.

His ERA is 4.41, but the number keeping it down is his BABIP-against: .253, well below the league average of .295 and noisy at just 80 balls in play. That gap is luck, not skill. Strip it out and his expected ERA is 5.06 — over half a run higher. His strikeout rate is solid (28.2%), but contact quality allowed is near league average, with barrel rate slightly above. Limited data: this call rests on the ERA-vs-xERA gap, which is driven by the unstable BABIP-against. The ERA is real on the scoreboard; the xERA is the truth. Sell high. 26 K and a 3.73 ERA with 7-13 SV is a sell-high window; trade into the regression before it hits.
