Crochet is a hold — the ERA overstates it, but the skill is below league.

His ERA is 6.30, and his BABIP-against is .350 against a league average of .295. BABIP-against needs around 800 balls in play to be reliable, and he has 86, so a large part of that inflated ERA is luck that will not hold. The problem is what the luck is hiding. Strip it out and his expected ERA is 5.12, a full run above league average. He misses bats — 26.8% strikeouts, 11.8% swinging strikes, 95.8 mph on the fastball — but he is also allowing hard contact at 45.3% and barrels at 10.5%, both above league. This call rests on the first stable sample of the season, with no baseline yet to lean on. Fade the panic and don't buy. Hold. At 0 K and 4.19 ERA ROS, he's a drop — deep-league streaming-only until the strikeout sample returns.
