Walker (foot) will get the start for Saturday's game against the Angels, Kevin Shockey of Seattle Sports Radio 950 AM reports.
Walker has been out since July with a foot injury that will require surgery during the offseason. He recently reached the last step in his recovery, joining Triple-A Tacoma for a rehab assignment Monday, and going 4.1 innings on the mound without a setback. Walker's start will push James Paxton's back to Sunday, giving him an extra day of rest.
