The Mariners have acquired starting pitcher Aaron Harang from the Colorado Rockies for a minor-league reliever Steven Hensley.
In order to make room on the active roster for Harang, the team designated reliever Kameron Loe for assignment. The Mariners have 10 days to trade, release or outright Loes contract.
Harang began the spring with the Los Angeles Dodgers but was traded to the Rockies for veteran catcher Ramon Hernandez. The Mariners were reportedly interested in Harang at the time.
The move comes after two bad starts by the Mariners No. 4 and No. 5 starters against the offensively-challenged Houston Astros. On back-to-back nights, the Astros pounded rookie Brandon Maurer and Blake Beavan.
