    In the right light, Duplantier looks like a durable future mid-rotation starter. His arm works well and he has plenty of velocity, sitting 90-95 mph in most outings. He flashes an above-average curveball that has some power. His changeup needs more work. But teams will be concerned by the shoulder injury that cost him all of the 2015 season even if it did not require surgery. Duplantier's arm slot sometimes wanders and he opens up too quickly at times leading to control troubles. A move to the pen would let him focus on his best two offerings, gain even another tick to his fastball, and tone down the command concerns, but Duplantier has been too good at Rice to not get at least a shot to start in pro ball. His status as a redshirt sophomore may make him tougher to sign, but Duplantier's excellent bounce back season and the lack of top-end college pitchers should entice a team to take him by the second round.
