Chase Burns yielded five runs — one earned — in five innings Tuesday in the first game of a doubleheader against the Guardians.

Unable to pick up his defense, Burns gave up a grand slam three batters after an Edwin Arroyo error in the first. He then allowed one more run on a José Ramírez single, two steals and a sac fly in the fifth. Burns’ velocity today was about one mph lower than usual. He remains a fine enough bet for now, but with the Reds fading from contention, he might not pitch much in September. He’s due to make his next start Sunday against the Pirates, though if that happens, it’d be just his second on four days’ rest in the last two months.
