Svanson is a hold — the ERA is inflated, but so is the skill underneath it.

His 7.27 ERA is not the whole story, and neither is the fix. His BABIP-against is .365 against a league average of .295, and that gap is luck — BABIP-against needs around 800 balls in play to be reliable and he has 143. When those bounces normalize, the inflated ERA comes down. But it does not come down to something worth buying. His expected ERA is 6.03, nearly two runs above the league average of 4.10, and it has been stepping up across the sample. He strikes out 19.8% of batters, below league, and walks 10.1%, above it. The panic is overdone, but there is no real pitcher hiding underneath. Hold. 0 SV and a 5.21 ROS ERA is a drop-tier tax — hold only as deep-league filler, not a real stash.
