PHOENIX -- The D-backs on Monday acquired right-handed pitcher Lucas Harrell from the Astros for a player to be named later or cash considerations.
Harrell was assigned to Triple-A Reno. The 28-year-old had a 9.49 ERA in three starts for the Astros this year after going 11-11 with a 3.76 ERA for Houston in 2012.
"I know a couple of years ago he had a really good year for Houston and not so good lately," D-backs manager Kirk Gibson said. "But I think the reports say that he still has a pretty good arm. We're looking for depth for sure."
With the season-ending injury to Patrick Corbin as well as the ineffectiveness of Randall Delgado and Trevor Cahill that prompted the team to remove them from the rotation, the organization's pitching depth has been tested.
To this point, the team has elected not to promote top prospect Archie Bradley.
The Harrell trade comes a couple weeks after the team signed veteran left-hander Randy Wolf and sent him to Reno.
