Traded to Los Angeles (AL) with Ty Buttrey for Ian Kinsler and cash considerations (July 2018)

Physical Description: Tall left-hander with a long, athletic frame. Has ideal pitchers frame and the body to add weight as he physically matures throughout his twenties. Looks the part.

Mechanics: Throws from a three-quarters arm slot, with surprisingly solid mechanics for a converted position player. Starts closed with hands by his chest. Has a high leg lift and turns his body before coming forward, which adds deception. Arm action works. Short behind. Repeatable delivery.

Fastball: 93-97 mph. Tops out at 98 mph. Velocity took a step forward during the 2017 season. Previously sat 90-93 mph and topped out at 95 mph. Average control, but needs to improve command. Potential plus offering.

Slider: 83-85 mph. Shows short, hard break. Has feel for and confidence in the pitch. Has shown the ability to bury it down-and-in to righties when ahead in the count. Potential above-average offering.

Splitter: 82-84 mph. Evolved from his changeup during the 2017 season. Flashed average potential with late downward action, but was inconsistent. Still a work in progress. Changeup was firm and straight, thrown sparingly.

Career Notes: Drafted as an outfielder and spent three years struggling mightily at the plate before converting to pitching during Spring Training 2014. Had prior experience pitching while growing up in the Dominican Republic. Moved to Brooklyn from the Dominican Republic at age 17 with his family.

Summation: Projects as a fringe, situational reliever. Ceiling of a solid middle reliever. Needs to improve command and consistency with secondary offerings. Has really taken to pitching and shown surprising feel for a converted position player. Has shown a strong work ethic and solid makeup. Stuff regressed somewhat during the 2016 season compared to 2015. Still misses bats, but command issues make him hittable.
