The Blue Jays claimed Waldron off waivers from the Padres on Wednesday.
Waldron will presumably slot into the bullpen in Toronto, where he'll provide the team with a right-handed arm capable of covering multiple innings. Toronto transferred lefty Patrick Corbin (shoulder) from the 15-day injured list to the 60-day IL in order to clear room on the 40-man roster for Waldron, who recorded a 7.16 ERA and 1.56 WHIP in 32.2 innings with San Diego this season.
