He can't leap tall buildings in a single bound, nor can he rescue the Josh Donaldson trade single-handedly. What Franklin Barreto might be able to do, however, is play major league baseball really well.
Always a solid prospect, Barreto's strong showing (.302/.333/.500) in A-ball at age 19 last year only moved him higher on prospect lists and the SS -- or is he? -- will not turn 20 until February. There are questions about whether any 19 year old yet to play at AA can hit, but if you believe scouts and results-so-far, in Barreto you gain a profile of a guy "whose bat will play in the big leagues," and maybe sooner rather than later.
