Marlins manager Clayton McCullough said Tuesday that Bellozo will be part of the team's Opening Day rotation, Christina De Nicola of MLB.com reports.
Bellozo was optioned to Triple-A Jacksonville earlier this month, but the Marlins are in need of reinforcements with Ryan Weathers (forearm) and Edward Cabrera (blister) going down. The 25-year-old Bellozo managed a 3.67 ERA for Miami last season, but that came with a 5.72 FIP. His leash in the role will be short.
