Astros pitcher Lucas Harrell will start with the club Friday, according to MLB.com.
Harrell will get the nod for the team's first game of the spring. He'll be following up by Matt Albers, Peter Moylan and Josh Fields. Both Fields and Albers are thought to be in contention for the closer role.
Harrell posted a 5.86 ERA in 153 2/3 innings last season.
