Devenski was recalled from Triple-A Fresno on Thursday, Brian McTaggart of MLB.com reports.
Devenski will replace Michael Feliz at the back of the Houston bullpen, after Feliz threw 107 pitches in mop-up duty during Wednesday's 16-6 loss to the Yankees. The 25-year-old Devenski had a nice spring and nearly made the Opening Day roster, but he'll probably get most of his work in low-leverage situations.
