The Reds optioned Legumina to Triple-A Louisville on Wednesday.
Legumina was sent back to the minors to clear a spot on the 26-man active roster for right-hander Levi Stoudt, who was activated from the taxi squad ahead of his scheduled start Wednesday versus the Rays. During his first taste of the majors, Legumina made two appearances out of the bullpen, striking out four over 4.1 innings while allowing one run on three hits and one walk.
