Under the current front office, the Dodgers have developed a bit of a reputation for finding diamonds in the rough in the bullpen.
In 2016, they unceremoniously signed Joe Blanton to a 1-year, $4 million deal before he had arguably the best season of his career (and then hung a few too many sliders in the postseason). Last season, they signed Brandon Morrow to a Minor-League deal. Morrow struggled in the minors, but was called up on May 29th and became a huge piece of the bullpen, appearing in 14 of 15 postseason games and was one of 24 relievers with a sub-1.
