The New York Yankees 2016 minor league season was so full of superb minor league pitching performances that it is easy to overlook the efforts of Adonis Rosa. Splitting his time between short-season Staten Island and the Low-A Charleston Riverdogs this year, Rosa set himself apart from the organization’s stable of intriguing low-level arms and is a definite “sleeper” prospect going into 2017.
The 21-year-old righty began this year in the New York-Penn League, allowing just five earned runs 34 IP (1.32 ERA) while striking out 20.6% of the batters he faced and walking just 5.3%. That performance earned him a mid-July promotion to full-season ball, where he continued to have success during his month and a half in the Riverdogs rotation.
