Bellatti cleared waivers Tuesday and was outrighted to Triple-A Durham, Marc Topkin of the Tampa Bay Times reports.
The 24-year-old righty was DFA'd on Friday to clear room for Oswaldo Arcia. After clearing waivers, the Rays outrighted him to Triple-A, where he figures to serve primarily as a reliever. He owns a 8.44 ERA across 5.1 innings of work at Triple-A this season.
