The Blue Jays recalled Pop from Triple-A Buffalo on Friday.
The trade of Yimi Garcia to the Mariners on Friday cleared a spot in the Blue Jays' bullpen, so Pop will come up from the minors to fill the opening. The 27-year-old righty owns a 5.90 ERA and 1.41 WHIP through 29 innings in the majors this season, and he'll likely be limited to middle relief while in Toronto. Jonatan Clase was optioned to Buffalo in a corresponding move.
