Romero is a sell — his expected ERA is rising above league.

His expected ERA is 4.85, .75 above the league average of 4.1, and he has faced enough batters for that number to be reliable. The gap is not bad luck propping up a weaker line — his xwOBA allowed is .337 against a league average of .315, and that number is stable too. He strikes out 22.1% of batters, almost exactly league average, and his walk rate is 8.8%, slightly worse. The strikeout and walk rates are both average, so there is no swing-and-miss skill carrying the profile. His swinging-strike rate sits at 9.0% against a league average of 11.0%. That expected ERA has stepped up across the sample, which means the gap is widening, not shrinking. There is no luck story to fall back on; this is the level he's at. Sell. A 4.45 ERA and 1.33 WHIP deliver no 5x5 value — drop him; waiver-wire arms are the better stream.
