Walker (elbow) was placed on the 60-day disabled list Friday. This is simply a procedural move, as Walker is already going to be out until sometime during the 2019 season after undergoing Tommy John surgery on April 25. His roster spot will be vacated to allow Kris Medlen to head to the majors to start Friday's game against the Astros.
Walker (elbow) underwent successful Tommy John surgery Wednesday. Manager Torey Lovullo said that "everything is as good as it can possibly be." This is a good sign for Walker, as he'll now put his focus on the lengthy rehab process. He'll look to return to action sometime during the summer of 2019.
Walker will undergo Tommy John surgery Wednesday in New York, Steve Gilbert of MLB.com reports. Walker was diagnosed with a torn UCL in his right elbow after exiting his start over the weekend with forearm tightness. He'll miss the reminder of the 2018 season and will begin the 2019 season on the disabled list as he works his way back.
Diamondbacks manager Torey Lovullo said Wednesday that Walker (elbow) was diagnosed with a torn UCL and will likely undergo Tommy John surgery. Walker exited his previous start April 14 with forearm tightness and was subsequently placed on the 10-day disabled list. He was later diagnosed with a UCL injury, and a second opinion ultimately confirmed the right-hander is dealing with a tear that will require surgical intervention. This is a brutal blow for both Walker and the Diamondbacks, as the 25-year-old owned a solid 3.45 ERA through three starts for the first-place club prior to suffering the season-ending injury. For now, Matt Koch is slated to start in Walker's place Friday, but Shelby Miller (elbow), who is recovering from a Tommy John procedure of his own, could end up settling in as the long-term rotation replacement by late June or early July.
An examination of Walker's forearm Tuesday revealed that he's dealing with a UCL injury, Steve Gilbert of MLB.com reports. While it's known that Walker suffered a UCL injury, manager Torey Lovullo was unsure if it's a tear. Per Gilbert, Walker is scheduled to receive a second opinion on the injury in New York in the coming days, after which it should be revealed how the righty will proceed and whether or not he'll require surgery.
