Lopez will move to a bullpen role going forward, Nathan Ruiz of The Baltimore Sun reports.
Although Lopez had a strong start to August, he struggled in his last two outings and allowed 11 runs across 5.1 innings during back-to-back losses. While manager Brandon Hyde didn't reveal who would take the right-hander's place in the starting rotation, the Orioles are hopeful that Lopez will perform better out of the bullpen.
