Scouting Scratch: High minors bullpen arms (5.28.15)

Physical Description: Thick, filled-out frame. Sturdy lower half. Limited projection with his body. Bigger than listed.  

Mechanics: High 3/4 arm slot. Short, jerky delivery. Arm short behind, with some deception from his body. Works quick, good rhythm.  Can struggle to finish his delivery consistently.

Fastball: 91-93 mph. Tops out at 95 mph. Solid-average potential. Heavy with late life. Jumps on hitters. Difficult to pick up. Has had trouble locating pitch arm-side. Two-seam has late arm-side run at 87-89 mph. Throws strikes, average command.  

Changeup: 82-84 mph. Solid-average potential. Solid arm speed, shows late dive. Potential to miss bats.  

Slider: 83-86 mph. Above-average potential. Short, vertical break. Sharp with tight rotation when at its best. Confident throwing the pitch in any count. Throws both a shorter, more cutter like version and longer, sweepier version. Used to throw a slurvey breaking ball 78-81 mph with short, 11-to-5 break.

Career Notes: Although he has worked out of the bullpen for most of his career, typically works longer outings, whether planned or due to consistent positive results. Signed later than most international free agents because of bouts with Dengue fever in 2008 and 2010.

Summation: Future 6th/7th inning reliever profile. Throws strikes, workable fastball/slider combination. Needs to improve changeup, and consistency with slider. Lacks late inning ceiling, but high floor.
