They’ll take their roster spots from Will Klein, who was placed on the injured list, and Cole Irvin, who was designated for assignment. In 20 starts at Triple-A Oklahoma this year, Irvin posted a respectable 3.58 ERA, but his underlying numbers were concerning. Nonetheless, in need of innings, the Dodgers gave Irvin the call on Friday when Brock Stewart hit the injured list. In his first MLB appearance in almost two years, Irvin threw six innings of relief, giving up six runs on eight hits. It surely wasn’t the comeback Irvin was hoping for, but to his credit, he looked better until his fifth inning of work.
