Amed Rosario, Mets

One of the most highly-rated prospects in 2017, Rosario is still trying to find his way in the big leagues. He hasn't been bad, with a .287 batting average, 15 homers, and 30 doubles. He just hasn’t made all that much of an impact (especially on defense where at times he struggles), but he’s still just 24 years old.
