With Konnor Griffin now in the big leagues, we have a new No. 1 prospect in baseball.

With that in mind, here’s an updated list of the top 50 prospects still in the minors, adjusted slightly for early performance and more than slightly when we have something more substantial to work with.A reminder that, for my midseason lists, I omit any players who are currently on a big-league roster, even if they have not yet reached the thresholds for rookie eligibility, so players like Bryce Eldridge, Trey Yesavage and Gage Jump are not on this list. Players who’ve already passed those rookie thresholds (130 AB, 50 IP, or 45 days on the major-league active roster) are always ineligible.I don’t use a model or any precise formula for these rankings, but because we are still in small sample-size territory — what you see here only reflects 2026 performance a little bit. New information, like someone adding a pitch or changing a swing, carries more weight, as does a significant injury that might affect a player’s short- or long-term outlook.
