The Rangers acquired left-handed pitcher Mike Kickham on a waiver claim from the Seattle Mariners and optioned him to Triple A Round Rock.
The club moved outfielder Ryan Rua from the 15-day to 60-day disabled list to make room on the 40-man roster. Rua has been out with a broken bone in his right foot.
Kickham, 26, was designated for assignment by the Mariners on Monday. He was 0-2 with a 7.29 ERA in 21 innings pitched in five starts. Opposing hitters are batting .243 against him. His last start on May 2.
Kickham was 0-3 in 14 appearances (three starts) with the San Friscisco Giants in 2013-14.
Rua was placed on the 15-day disabled list on April 11 with a non-displaced fracture in his right heel on April 10. He is eligible to come off the 60-day DL on June 10.
