Dynasty: Theo Gillen. The FanRanked staff dynasty board has Gillen ahead, Gillen #121 and Sloan #171, and the expert consensus agrees (#115 and #102). The community rates them even, FRV 54.4 and 51.7.
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.
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.
