The Diamondbacks hope Walker (finger) will be ready to return from the disabled list to start Wednesday against the Tigers, Nick Piecoro of The Arizona Republic reports.
Walker was placed on the 10-day disabled list May 21 with a blister issue and has progressed well through his rehab program. He was able to pitch a five-inning simulated game Wednesday and tossed a bullpen session Saturday, enduring no apparent complications. Walker may throw again Monday before the Diamondbacks make a final call on his status for Wednesday's start. Assuming he's able to go, Zack Godley or Randall Delgado would likely lose his spot in the rotation, Nick Piecoro of The Arizona Republic, though Patrick Corbin has pitched poorly enough that he could be under consideration, as well.
