Gose is expected to share duties in center field with Rajai Davis, and hit against righties.
The speedy 23-year-old Gose was batting .239 with a .316 on-base percentage, three home runs, 27 RBIs, 64 runs scored, and 22 stolen bases in 35 tries for Buffalo. He hit .304 in 26 plate appearances earlier this season for the Blue Jays, and is a career .233 hitter in 69 games in the Major Leagues.
Mickey Storey was sent down to Buffalo to make room for Gose, the righty having pitched only one-third of an inning since joining the club last Saturday.
