The Blue Jays recalled Tate from Triple-A Buffalo on Wednesday.
Tate posted a 4.59 ERA and 1.41 WHIP through 33.1 innings with the Orioles before being DFA'd by the club in August. However, he's given up just one run over five innings since joining the Jays organization Sept. 1, and he'll now return to the majors to give Toronto's bullpen a fresh arm. Luis Frias was optioned to Buffalo in a corresponding move.
