Marlins optioned RHP Ryan Gusto to Triple-A Jacksonville.

Gusto was lit up for three runs in just three innings against the Rockies on Thursday and hasn’t made it through the fifth inning in any of his six starts with the Marlins, culminating in a troublesome 5.55 ERA. He’ll attempt to work through his issues at the Triple-A level for the time being. William Kempner was recalled from Triple-A Jacksonville in a corresponding move on Friday.
