Dynasty: Franklin Arias. The FanRanked staff dynasty board has Arias ahead, Arias #115 and Gillen #121, but the expert consensus has Gillen ahead (#102 to #109). The community rates them even, FRV 52.4 and 51.7.
JD on Franklin Arias (Jul 3, 2026): Arias may need to be re-evaluated as he is killing it at AA right now. I just don’t love that he is undersized and worried he will have more of a contact focused approach at the big league level. Realistically he should probably be climbing closer to the top 20. I'll probably be re-evaluating over the next couple of weeks.
JD on Theo Gillen (Jul 28, 2026): Theo Gillen really snuck up on me this year - I had never really given him much love because there is no power in his profile yet. Now that he has tapped into that potential, the ceiling is all of a sudden a lot higher. He has clubbed 16 home runs across two levels this year and has held his own with a 130 WRC+ in AA across 101 plate appearances. He may not have as high an end-of-ceiling as some of the top prospects but his floor is as high as anyone in the minor leagues. I think he will be a very exciting prospect when he debuts in late 2027 or early 2028. I probably won't be as high on him as some others are (our aggregated expert rankings have some analysts putting him in their top 10) but he is solid, the top 20 prospect for me.
