Graceffo is a sell-high — his ERA is running on lucky outs.

His ERA is 2.70, but the outs behind it have come too easily. His BABIP-against is .207, 88 points below the league average of .295, and that number is not reliable at 204 balls in play — it needs around 800. When batted balls start finding grass instead of gloves, the ERA moves. The stable numbers already point that direction: his expected ERA is 4.50, 1.80 runs above the surface, and that gap has been stepping up across the sample rather than shrinking. He strikes out just 18.2% of batters against a 22.0% league average, and he walks 11.0% against 8.0%. A modest strikeout rate and shaky command leave no foundation under the line. Sell high. 2 K, 4.22 ERA, 1.37 WHIP rest of season says drop — deep-league streaming-only arm, not the sell-high asset the inflated line implies.
