Lynch is a sell-high — BABIP luck is inflating his ERA.

His ERA sits at 2.35, more than a run and a half below league average, but the skill metrics do not back it. His BABIP-against is .210, 85 points below the .295 league average — a staggering gap. BABIP-against needs around 800 balls in play to be reliable; he has 107. That is luck, not repeatable skill. Strip it away and his expected ERA is 3.33, nearly a full run higher than the box score. His strikeout rate and walk rate are near league averages, and his hard-hit and barrel rates are slightly suppressed but not elite. There is no stability story here: limited data — this call rests on a gap that will not hold. Sell high. 23 K / 3.69 ERA / 1.24 WHIP is a deep-league sell window before luck regresses and the line falls.
