The Seattle Mariners placed left-hander Wade LeBlanc on the 10-day injured list Sunday with a strained right oblique.
The Mariners recalled right-hander Erik Swanson from Triple-A Tacoma in a corresponding move.
LeBlanc, 34, left Friday’s start against Houston with two outs in the fifth inning. He is 2-0 with a 4.50 ERA in three starts this season.
Swanson, 25, was sent to Tacoma after making his major league debut in Thursday’s 7-6 win at Kansas City. He allowed two runs on three hits in two innings of relief, striking out four and walking two.
