Kelly (8-9) took the loss Sunday against the Guardians, allowing five runs on eight hits and four walks while striking out five over five innings.
Kelly surrendered a leadoff solo homer to Patrick Bailey in the third inning as part of a two-run frame. The right-hander ran into more trouble in the fifth, when five consecutive Cleveland batters reached safely, resulting in three more runs. Arizona's offense offered no support, as the Diamondbacks were shut out in the defeat. The four walks matched Kelly's highest total since April 28. He'll carry a 5.04 ERA, 1.49 WHIP and 76:46 K:BB over 114.1 innings into his next scheduled start Friday against the Dodgers.
