Devenski was optioned to Triple-A Durham on Monday, Tricia Whitaker of Bally Sports Sun reports.
Devenski holds a 4.15 ERA in six relief appearances since joining the Rays earlier this month. He's being moved off the 28-man active roster in favor of Jalen Beeks, who was called up from Durham to give the Rays another left-handed option out of the bullpen.
