The Blue Jays recalled Robertson from Triple-A Buffalo on Saturday.
Eleven days after being claimed off waivers from the Angels, Robertson will join the Jays' bullpen in order to provide the team with another fresh arm heading into the final two games of the season. The 26-year-old righty owns a 4.38 ERA and 1.38 WHIP through 12.1 innings in the majors this season but will likely be limited to low-leverage situations, given his 7.36 ERA in Triple-A. Easton Lucas was optioned to the Florida Complex League in a corresponding move.
