Cruz is a sell-high — his ERA is BABIP luck, not skill.

Limited data, but the signs are clear: his 2.25 ERA does not match the underlying skill. The gap is driven by his BABIP-against, .275 — below the league average .295 — with only 93 balls in play. BABIP-against needs around 800 to stabilize, so that suppressed number is luck, not repeatable ability. His xERA sits at 2.89, well above the actual ERA, pointing directly at regression. The raw stuff is real — a 29.9% strikeout rate and 18.1% swinging-strike rate, both well above league — but the run-prevention is being flattered by batted-ball fortune. When the BABIP normalizes, the ERA will rise toward the xERA. Sell high. With 28 K but a 3.67 ERA / 1.25 WHIP, sell into the inflated line; this deep-league window won't last.
