Medeiros was their 13th ranked prospect. Former 1st round pick in 2014.
Scouting grades: Fastball: 55 | Slider: 60 | Changeup: 50 | Control: 45 | Overall: 45
The Brewers made Medeiros the highest-drafted prep to come out of Hawaii, selecting him 12th overall in 2014 after he blew away the club's front office during a pre-Draft workout at Miller Park. He's continued to impress with his pure stuff in the professional ranks, though the results have been uneven at times. After a rocky 2016 season at the Class A Advanced level that saw him miss time with back and groin injuries as well as the flu, Medeiros returned there in 2017 and showed bat-missing ability more on par with his stuff -- a trend that continued for him in 2018 in his first Double-A campaign.
Getting away from his low-three quarters arm slot in '16 cost Medeiros both velocity and life on his fastball. Bigger and stronger in '17, he looked more like his old self in the Carolina League, operating at 92-95 mph with a heavy fastball. His slider remains a plus pitch, one capable of inducing whiffs on both sides of the plate with its significant lateral break, and he'll also flash above average with his changeup, which has good sink and fade. Medeiros' control continues to be below average, but he was markedly better in that regard in '17, issuing a career-best 3.7 walks-per-nine, down from 6.7 the previous year.
The jury is still out on whether Medeiros, with his unique arm slot and underwhelming control profile, can remain a starter long term. The Brewers think he can, believing that the Hawaiian southpaw will eventually learn how to harness his dynamic three-pitch mix. If he can't, however, it's widely agreed on that Medeiros will have impact potential in a big league bullpen.
