Morillo (0-1) was tagged with the loss Saturday, allowing two runs on one hit and one walk over two-thirds of an inning in a 3-2 loss to the Dodgers.
Morillo got the first two outs in the eighth inning before walking Mookie Betts, which set the stage for Will Smith's two-run home run. Arizona manager Torey Lovullo has tabbed Morillo as an option against lefty batters in Arizona's all-righty bullpen, and he successfully navigated Shohei Ohtani and Kyle Tucker before giving up the runs.
