Burdi was optioned to Triple-A Durham by the Rays on Friday, Tricia Whitaker of Bally Sports Sun reports.
Burdi threw a total of three innings over two appearances the last two days and didn't allow a run. Unfortunately, it also meant he probably wouldn't be available for at least a day or two and that might have cost him a roster spot. Burdi figures to be back in the majors down the road when the Rays need bullpen reinforcements again.
