Diamondbacks righty Shelby Miller has hired Roc Nation Sports and agent Kyle Thousand to represent him, Liz Mullen of the Sports Business Journal reports on Twitter. Miller, who’s still just 26 years of age, underwent Tommy John surgery in mid-May. So long as his recovery goes well, he ought to be ready to go at some point in the middle of the 2018 season. Through 22 innings, Miller had shown some signs of bouncing back from a rough 2016 campaign. In particular, the right-hander was working at a career-high 95.4 mph average fastball velocity and 9.6% swinging-strike rate — though he also allowed a dozen walks to go with twenty strikeouts. Arizona will have to think hard about whether to tender Miller a contract, though odds are the team will deem it a worthwhile risk. Miller won’t command much of a raise on the $4.7MM salary he commanded for 2017, and he’ll still be controllable for another season through the arb process.
