Astros recall LHP Dallas Keuchel
Keuchel was scheduled to arrive in Houston before Saturday night's game against Oakland. He went 3-8 with a 5.27 ERA in 16 starts for the Astros last season. He is expected to work as a long reliever this year.
Blackley, who was acquired from Oakland on Thursday, strained his left shoulder in a bullpen session on Friday. His time on the disabled list is retroactive to Friday.
