Barnes was recalled from Triple-A Buffalo on Monday, Ben Nicholson-Smith of Sportsnet reports.
Barnes was returned to the minors after serving as the Blue Jays' 26th man for a doubleheader last Thursday, but he didn't make any appearances for Buffalo over the weekend. As a result, Barnes should be available out of the bullpen immediately upon rejoining the Blue Jays ahead of Monday's series opener with the Yankees, but don't expect manager John Gibbons to hand him much high-leverage work during his time with the big club. Aaron Sanchez (finger) was placed on the 10-day disabled list to facilitate Barnes' promotion to the 25-man roster.
