Dynasty: Franklin Arias. The FanRanked staff dynasty board has Arias ahead, Arias #46 and Sloan #162, and the expert consensus agrees (#111 and #113). The community rates them even, FRV 53.0 and 55.7.
JD on Franklin Arias (Oct 21, 2026): I didn't just want to assume that I should be ranking prospects by their industry average slots, so I've been taking deep dives on every prospect that was in consideration for the top 50. I came away from that ULTRA-hyped on Franklin Arias, and I would hear arguments to have him number 1 overall. I'm not surprised the Red Sox were willing to get rid of Marcelo Mayer knowing they had this demon waiting in the wings. Arias tore up two levels of the minors this year, slashing .323/.406/.557 and hitting 25 homeruns across 520 PA. Potentially even more impressive were his swing decisions, with only a 14.2% K rate vs a 10.2% BB rate. For someone who put up this kind of power in the upper minors, its a rare skill set to have this combination of power, patience, and contact quality. I'll be honest, the swing is the one thing the concerns me. This is 100% an eye test take (so take it with a grain of salt) but the swing looks like it can get too long and loopy, and I'm not sure how it holds up at the big league level. It's one thing to rely on your raw athleticism when you are in the minors and velos and breaking balls aren't as good, but at the big league level if you have to cheat to catch up to velocity you are going to get exposed. I am really splitting hairs here, so don't let it dissuade you from treating Arias like the high quality asset that he is. Just don't be surprised when these elite K rates regress at the big league level and the average drops with it. One final note for what it is worth: Arias has the best 7 year projection of any prospect we track. A 2027 debut would be electric, and would expect him to see him after the ASB if things go right.
JD on Ryan Sloan (Jul 3, 2026): For Sloan, his ranking has less to do with his skill set and more to do with how I value pitching prospects in dynasty leagues. My motto is “there is no such thing as a pitching prospect”, which is an exaggerated way to say that I would rather invest my prospect capital in a hitter because pitchers are so susceptible to injuries and their value evaporating before they have a chance to hit the big league level. Sloan is the #4 non-debuted SP (behind Hernandez, Anderson, and White) on my list, I would look at them that way rather than his ranking compared to all of the hitters and debuted pitchers overall. I’m very bullish on him long-term, but from a dynasty prospect perspective, pictures are hard to rank incredibly high.
