Dynasty: Theo Gillen. The FanRanked staff dynasty board has Gillen ahead, Gillen #67 and Sloan #162, and the expert consensus agrees (#113 and #98). The community disagrees, leaning Sloan, FRV 55.7 to 50.9.
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 (Nov 5, 2026): Oh, do the Rays have another top prospect to salivate over? I can't help but think that Theo Gillen should have been getting at-bats in the playoffs for the Rays. The combination of DeLuca, Vilade, Williamson, and Walls feeling like automatic outs at the end of their lineup was ridiculous. Theo Gillen really took another step forward this year, hitting 22 home runs after hitting only 5 across his first two minor league seasons. That was really the one piece missing and the piece that I wasn't sure would ever develop when he was first touted as a top prospect. When you pair that with a .968 OPS and a double-digit walk rate, he looks like he will be a mainstay in the big leagues for years to come. I feel like Carson Benge is a pretty good comp to Gillen. I think if he gets a full season of at-bats next year, he could put together a similar standout rookie campaign. That would catapult him into (or close to) the top 25 dynasty rankings at the end of 2027 heading into 2028.
