SEATTLE -- The Seattle Mariners optioned starting outfielder Nori Aoki and relief pitcher Tom Wilhelmsen to Triple-A Tacoma on Friday to clear space for pitching reinforcements.
The Mariners made seven roster moves before starting a homestand against St. Louis. The Mariners also placed right-hander Adrian Sampson on the 15-day disabled list and brought up left-handers Wade LeBlanc and David Rollins and right-hander Donn Roach from Tacoma. Seattle also transferred right-hander Tony Zych to the 60-day DL.
LeBlanc was set to start for Seattle on Friday night. It's his first start in the majors since 2014.
