Oviedo signed for a $375K bonus in 2015, and he has progressed quickly through the system since. After starting 2018 in Extended Spring Training, he dominated in nine New York-Penn League starts before a late bump to the Midwest League. He was shut down in August with a lower back/glute issue, but it isn’t seen as a long-term concern. All looked well during my backfields look, where Oviedo showed off a deep mix of stuff and was throwing free and easy.
Oviedo requires projection but has all the ingredients of a solid big league starter. His 6-foot-4 frame oozes projectability, and he repeats a low-maintenance delivery well enough to grade up on his control. Listed at 170 pounds, he has added muscle in the last year and now appears broader than that. The fastball touches 96 mph at best and generally sits 90-to-94 mph, showing solid run when angled down in the zone. It exploded to his armside at times this look, diving away from barrels very late. Oviedo already can throw both a slider and curve with distinct action from one another, the slider flashing swing-and-miss upside at best. He also shows feel for a changeup, giving the foundation of a four-pitch mix.
Ticketed for Low-A Lake County to start 2019, Oviedo is on the short list of potential breakout arms in full-season ball this year. His mix of size, delivery, stuff, and control give the upside of a mid-rotation starter.
