The Blue Jays recalled Vasquez from Triple-A Buffalo on Monday.
The addition of Vasquez gives the Blue Jays another healthy left-handed option out of the bullpen after southpaw Tim Mayza (forearm) was moved to the 15-day injured list in a corresponding move. Vasquez previously made three relief appearances for Toronto earlier this season, covering 2.1 innings in total and giving up four earned runs on four hits and two waks.
