Duarte is a sell-high — his 2.12 ERA is BABIP luck.

His ERA is 2.12, and the number propping it up is his BABIP-against: .197, nearly 100 points below the league average of .295. BABIP-against needs around 800 balls in play to be reliable, and he has 74. That gap is luck, not skill. Strip out the noise and his expected ERA is 2.87 — 0.75 runs above the actual figure, and that gap is the regression coming. The skill metrics underneath are solid but not dominant: he strikes out 26.8% of batters, a bit above league, and his hard-hit rate allowed of 24.3% is well below the 40% league mark. There is real ability here, but the ERA is running well ahead of it. With no track record and only 112 batters faced, this is a limited-data call resting on the first sample of the season. Sell high while the surface line still holds. With the 3.70 ERA / 1.24 WHIP ROS line projecting the fall, that deep-league trade window is open — sell before the surface cracks.
