The Brewers selected the Hawaiian southpaw from the prep ranks in 2014, giving him $2.5 million to forego his commitment to Pepperdine University. Medeiros has worked steadily up the ranks as a starter, although his mechanics and lack of control project best into the bullpen long-term.
In my viewing June 16, Medeiros was working his fastball 90-to-92 mph with a funky, slingy arm action from low ¾’s that is very difficult on left-handed hitters. The pitch has late action and tailing life up in the zone, showing sink down in the zone which worked well against righties when he kept it close enough to the outer edge. Medeiros’ command projects to fringe average out of the pen, as he lacks the physicality and consistency to repeat for long stretches. His command backed up on him as his 96-pitch outing wore on. Medeiros spins a quality 1-to-7 curveball at 77-to-78 mph, working well front door to lefties. He was careful with it to right-handed bats, and from his wide angle, it’s more of a swing-and-miss pitch to same-side hitters. Medeiros has an average changeup as well, and he may keep it as a second look against righties out of the pen.
Medeiros might have the stuff to sneak into the rotation, though I see him profiling better in the bullpen. There’s less pressure on his command in short stints, and his two above-average pitches fit as a middle reliever who can face both righties and lefties.
