Diamondbacks' Shelby Miller: Decides on Tommy John surgery

Miller (elbow) will undergo Tommy John surgery to repair the torn UCL in his right arm, Tommy Stokke of FanRag Sports reports.

Analysis:

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.
