Manager Scott Servais said Wednesday that he believes Walker (foot) will be ready to go next week, Shannon Drayer of 710 ESPN Seattle reports.
This echoes the team's sentiment from earlier in the week that, despite Walker being scratched from Friday's start, he should be able to avoid the disabled list. Walker is dealing with posterior tibial tendinitis, which stems from the right-hander having extremely flat feet, and the issue is aggravated every time he pushes off the pitching rubber.
