The Blue Jays claimed right-hander Mickey Storey off waivers from the Astros on Wednesday.
Storey made 26 relief appearances in 2012, going 0-1 with a 3.68 ERA in his first big league season. The 6-foot-2, 185-pound righty posted a .237 average against, including a .167 mark against left-handed batters.
He was originally selected by the A's in the 31st round of the 2008 First-Year Player Draft.
The claim caps Toronto's 40-man roster.
