Duran has a couple monster pitches and has not logged a FIP over 3.93 in full-season ball, but he may fit best as a power reliever long term. A 6-foot-5, 230-pound righty who headlined Minnesota's return for Eduardo Escobar in the 2018 deadline deal with Arizona, Duran's best skill is an ability to generate groundballs at an elite clip (65.4 GB% at Low-A, 52.9 GB% at High-A, 63.3 GB% at Double-A since joining the Twins). He accomplishes this with a four-seam fastball that can touch triple digits and a unique low-90s split-fingered sinker -- both rate as plus-plus pitches. Duran could easily slot into a big-league bullpen as is and have success. In order to make it as a starter at the highest level, however, he will need to turn his curveball into a reliable third pitch while demonstrating at least fringe-average command. Look for him to spend the bulk of 2020 in the upper levels of the minors.
