26 Shelby Miller SP

Miller (elbow) underwent Tommy John surgery Wednesday, Steve Gilbert of MLB.com reports.

Miller will now begin a long recovery process with the hopes of returning to the mound for the Diamondbacks some time near the end of next summer. Manager Torey Lovullo said that he expects Miller to miss about 15 months, but that timetable could be adjusted once the right-hander draws closer to throwing. Zack Godley was recalled from Triple-A Reno on Wednesday and figures to assume Miller's spot in the rotation for the foreseeable future.

Miller, who was placed on the 60-day disabled list last Thursday, indicated over the weekend that he would opt for the season-ending procedure. Recent protocol for Tommy John rehabs have typically included a 14- or 15-month recovery timetable, according to Nick Piecoro of The Arizona Republic, making it unlikely that Miller will be back on the mound for the Diamondbacks until July or August of next season. With that in mind, Miller looks bound to open the 2018 campaign on the DL, which may make him little more than a late-round stash consideration in NL-only and deep-league drafts next spring. The Diamondbacks will replace Miller in the rotation with Triple-A Reno starter Braden Shipley, but the 25-year-old may need to pitch well to guarantee himself any outings beyond Thursday's turn against the Nationals.

Miller made his decision after meeting with multiple doctors, though his transfer to the 60-day DL effectively foreshadowed an end to his 2017 season. The 26-year-old was trying to improve upon his dismal 2016 showing, when he posted a 6.15 ERA and a 1.67 WHIP over 20 games in his debut season with Arizona. Instead, he'll undergo the dreaded procedure, which will keep him out 12-18 months, meaning he'll be in line for a return late next season, if that. The D-Backs, meanwhile, will have to move on with Zack Godley or another replacement in the rotation.

This move comes as no surprise, as it was recently reported that Miller is dealing with a partial UCL tear that may require Tommy John surgery. In addition to the UCL tear, Steve Gilbert of MLB.com reported that Miller is dealing with a flexor strain. In a corresponding move, Arizona recalled T.J. McFarland from Triple-A Reno.

Miller is currently exploring his options to determine whether or not Tommy John surgery is the best course of action. Regardless of the choice he ultimately makes, Miller is on track to miss an extended period of time to the injury. After Miller was placed on the DL, Zack Godley was brought up from Triple-A Reno to join the Diamondbacks' rotation.
