Campbell gets a wide variety of opinions from scouts, and both the good and bad were on display last Saturday during his season debut. He held an effortless mid-90s fastball through a four-inning outing, striking out seven Bucknell hitters despite bouts of wildness. He also labored extensively at times—especially from the stretch—fighting to repeat his delivery and needing nearly 20 pitches an inning to get through the start.

An ultra-athletic 6’5’’ and 225 pounds, Campbell looks more like an NBA shooting guard than a pitcher. His arm is extremely fluid through a high three-quarters slot, generating an easy 92-to-94 mph fastball that can touch 96 late into games. For as well as the arm works out front, it isn’t without serious effort in the arm-circle, raising questions about his durability if used in the rotation over a long professional season. That Campbell has already taken a redshirt after missing most of 2017 with an elbow injury only adds to scouts’ injury concerns. A changeup at 81-to-84 mph was the better of his two pitches last weekend, showing glimpses of solid-average fading action away from lefties when thrown with fastball arm speed. His breaking ball is soft and loopy at 71-to-74 mph, though a pitcher with his size and arm action might be better suited moving to a slider and/or cutter at the next level to combat same-side hitters.

Campbell will be watched closely for his size, athleticism, and velocity leading up to the draft. No one questions the raw ingredients here—it’s his consistency that will dictate his placement on team’s boards when June rolls around. The additional leverage he carries as a draft-eligible sophomore might also be a factor. He’s certainly athletic enough to adjust his mechanics and arsenal, though it’s easy to see Campbell emerging as a power-armed relief prospect at the professional level.
