McClanahan is a sell-high — his ERA is propped up by luck.

His ERA sits at 3.36, but the number holding it there will not hold. His BABIP-against is .255, 40 points below the league average of .295, and BABIP-against needs around 800 balls in play to be reliable. He has 337. That gap is luck, not skill. Strip it out and his expected ERA is 4.26 — nearly a full run above what the box score shows, and that expected ERA has been stepping up across the sample. His strikeout rate, 21.8%, is exactly league average, and his walk rate, 8.0%, is too, so there is no dominant stuff story to lean on when the batted-ball luck normalizes. He is a good pitcher having a fortunate stretch. The market is paying for the stretch. Sell high. 13 K and a 4.20 ERA ROS says the sell-high window is the play — a drop-tier arm once the luck normalizes.
