He's got the build and frame of a starter, but he doesn't have the variety or stamina to start.
Variety -- he throws two fastballs, generally with good location, and a knuckle curve. Those are good pitches, but his cutter and changeup rarely fool anybody. His cutter moves like a slower fastball: it doesn't cut. Those secondary pitches have almost been discarded, and for good reason, but limited variety means limited deception, especially multiple times through the order.
Stamina -- Workman loses velocity after his first inning, and again after his third. By the time he's over 50 pitches, he struggles to hit 90 mph. In his first inning, he often averages 93, touching 94, but it doesn't last.
Workman is 26, so I wouldn't count on much more development from him. If he is what he is, what he is is a reliever.
