Listened to an interesting podcast today that had a short interview with Callis in it. He expects that Arias or Rod-A as some are calling him to be the #4 or 5 spec in our system once he signs. I haven't heard this anywhere else, but these guys were saying if Arias comes close to reaching his ceiling that he would be the Yanks SS of the future. That was including Volpe, Peraza, Vargas and Sweeney.
They believe all his future grades that are out now are about a half grade to low, especially defensively. I hate the comp but they said defensively he reminds them of a young Correa. Pluss, plus arm, is always in position to make the plays he supposed to and has the athleticism to make the ones most other SS don't.
Offensively they seem to love everything about the kid. They believe his feel, approach and power all play like someone who is much, much older.
They said they difference they see between Dom and Arias is that Dom is all raw tools, ceiling and projections while Arias tools are more developed at a younger age.
From what i can tell Arais has to the chance to be one of those rare kids who could be MLB ready before he turns 21
