Amed Rosario wasn’t always regarded as a top flight prospect. Some had questions about his ability back in 2012 when the Mets signed him as an international free agent out of the Dominican Republic.
Some scouts believed that Rosario’s 6-foot-2 frame would fill out, and as he added muscle, his power would develop. There were concerns that a bulked-up Rosario would outgrow shortstop and be forced to move to third base.
Others wondered whether he’d be able to carry enough weight to hit for power. After going deep just five times over his first three minor league seasons—including a 2015 season that saw him go without a home run—it seemed as if the power would never come.
