Acuna is a very good talent, likely to rise fast in the prospect lists.
After that I think we have a large group of good but not elite position prospects. In rough order of how I rank them: Yepez, Ruiz, Riley, Peterson, Isranel Wilson, Dyskra, Herbert, Davidson. Right now I would not project any one of them individually as an average to above average ML regular. Rather they profile as platoon or bench players. But given we have eight of them, I feel comfortable predicting one of them will make it as a regular. Just don't know which one at this point.
So I would predict that four regulars will emerge from the current group in the minors. Albies, Swanson, Acuna and one more.
We also have a third group out of which some useful bench players will emerge: Camargo, Lien, Ventura, Valenzuela, Salazar, Obregon, Jonathan Morales, Didder.
Finally, there are the international signings who have not played yet: Derian Cruz, Christian Pache, Juan Morales from last year; Maitan, Guttierez and others from this year.
I think there is a lot of positional talent. It is true that much of it is far from the majors. But in terms of overall positional talent, it is a strong group.
