Gage's contract was selected by the Blue Jays on Monday, Arden Zwelling of Sportsnet.ca reports.
Gage is a 29-year-old lefty with no big-league experience to his name. He's showed promise for Triple-A Buffalo this season, however, posting a 1.08 ERA and 32.3 percent strikeout rate in 16.2 innings of relief. Jeremy Beasley was optioned in a corresponding move.
