In a sense, Brandon Brennan is already a success story for the Mariners. Few Rule-5 Draft picks stick with their teams long term. The solid numbers he put up in 2019 assured him a spot in the 2020 bullpen, with a shot at high-leverage work among an injury-prone and unproven assortment of arms. Sadly, Brennan spent most of this past season out of commission between two different injured list stints. The 2021 Mariners have already added a pair of relievers and should add more, but for now Brennan has a shot at opening the season in the M’s middle relief role as a groundball specialist.
