Broad shoulders, tapered waist, plenty of room for projection, looks taller than listed height; true-three-quarters arm slot, plus arm speed, short arm circle in the back, hides the ball well; drop and drive delivery, drives hard with the lower half; athletic player, mechanics can get unbalanced and stiff at times to hurt command
Mauricio Rubio Jr.
Quad Cities River Bandits (Low A, Astros)
60: No. 3 Starter
Plus arm strength; plane with hard run, generates ground balls with offering; held velocity deep into game, projects to add some velo as he builds strength
11-5 shape, sharp bite and depth; has natural feel for spin, stays on top of the offering and uses it effectively against lefties and righties alike; present average command, will miss bats at the highest level with consistency
Plus fade and tumble; plus deception, potential to miss bats against both left- and right-handed hitters; command is inconsistent, still developing feel for the offering
11-4 shape with short movement; only threw three in game, flashed average potential major-league utility
FB Command: 40/50
Secondaries Command: 50/50
Abreu has a big arsenal with a wipeout curve and a change that also projects to plus. His inconsistent mechanics will keep him from becoming a true front-line starter, and the deficiency introduces a fair amount of risk to the profile. But it's a relatively straight path to his projection as a mid-rotation anchor who can pitch above that on days he reigns in his fastball command.
