Compact frame, narrow build, filled out; moves well off the mound, moderate athleticism; full stretch, quick leg kick, coils top half, short arm action; pulls hips, short stride to third base side, pole vault action over front side, hard drive away from target, firm strike, inverted; lunging motion, throws across body from three-quarter slot, unique arm angle and motion creates rare release point, extreme deception, very difficult pick-up; whip in follow-through, fluid recoil; 1.34-1.41 to home, varies timing

Curveball grip, slurvy shape, moderate horizontal action, mild two-plane movement, lacks tilt, trackable trajectory; consistent arm speed, excellent deception, extremely difficult pick-up, solid-average command; works it into the zone, provokes chases, moderate swing-and-miss potential
Straight change, mild fade with some tumble, shows some feel, will lose it above the zone; tunnels well, mild deceleration, confidence in the pitch, will throw it down in the count
A 24th round pick out of Nevada in 2014, Blueberg is an undersized right-hander with an extremely funky motion. He creates a unique angle of attack for an average three-pitch arsenal that plays up significantly on account of the deception he creates and solid north-south command. At-bats against him are uncomfortable affairs; batters struggle to time him, and there's enough raw stuff to take advantage of it. He responds well in tight situations and demonstrates high-leverage mentality.
Blueberg projects as a lethal right-on-right guy in a good bullpen, with the potential for a stretch or two in a primary setup role if the command sharpens a bit more.
