The Blue Jays traded Juenger to the Athletics on Saturday in exchange for minor-league catcher Owen Carapellotti.
After being designated for assignment Tuesday by Toronto, Juenger finds a new home with the Athletics. The 25-year-old appeared in just two games for the Blue Jays, allowing three earned runs on two hits and two walks in two innings. The A's DFA'd Brett Harris to make room on the roster for Juenger.
