Ginn is a sell-high — his ERA overstates the skill.

His ERA sits at 3.67, but the number keeping it low is his BABIP-against: .255, 40 points below the league average of .295. BABIP-against needs around 800 balls in play to be reliable, and he has 289. That gap is luck, not demonstrated run prevention. Strip out the noise and his expected ERA is 4.07 — well above the surface line. His strikeout and walk rates are near league average, and his contact-quality numbers (allowed hard-hit rate, barrel rate, xwOBA) all sit roughly at or just below the league mean. There is no elite-stuff story to fall back on when the BABIP normalizes. Limited data: this call rests on the reliable skill metrics suggesting he is closer to a league-average pitcher than the ERA indicates. Sell high. 49 K, 4.07 ERA, 1.37 WHIP, 2-4 W, 0 SV: a streaming-only option once the BABIP luck fades.
