The Blue Jays recalled Dallas from Triple-A Buffalo on Monday.
Dallas has been pitching exclusively in relief lately, logging a 2.65 ERA and 21:8 K:BB over 17 innings over his last 12 appearances (11 with Buffalo, one with Toronto). He'll be available for multiple innings out of the bullpen Monday versus the Orioles, and there's a good chance he'll be needed since starter Trey Yesavage (knee) will make an abbreviated start in his return from the IL.
