Tyler Wells
Wells is a sell-high — his 2.38 ERA is running on luck.
The 2.38 ERA on the scoreboard has a lot of fortune baked into it. His BABIP-against is .223 against a league average of .295, and BABIP-against needs around 800 balls in play to be reliable. He has 185. That gap is luck, not command, and it is the main thing holding runs off the board. Strip it out and his expected ERA is 2.94 — still good, but a half-run worse than the surface, and it has been sliding as the sample grows. The underlying skill is real enough: a 26% strikeout rate above league, a 6.5% walk rate below it, 16% swinging strikes. He is a good pitcher whose ERA is being sold to you as a great one. Sell high. The 2.94 ERA / 1.14 WHIP is the real line — a trade window, sell the inflated mark before it corrects.
