Sewald retired the lone batter he faced in the eighth inning of Saturday's 3-2 loss to the Dodgers.
Arizona led 2-1 in the eighth inning with Sewald warming up in the bullpen, presumably to save the game in the ninth, but he never got the chance after Juan Morillo allowed a two-run home run, setting up Sewald to get the final out of the inning in a non-save situation. It was the veteran right-hander's first appearance of the season.
