The most in-depth prospect rankings that are free come via Fangraphs. The 2023 list for the Astros just dropped:

Here are a few thoughts:
- Fangraphs is higher on the Astro system than many other outlets, seeing it as middle of the pack (if you include Brown and Y Diaz)
- They’re very willing to buck convention; they’re way down on guys who are liked (Dirden, Pedro Leon), and have even revised rankings of guys they used to like (Colin Barber, Jairo Solis).
- The biggest shock is the 50 grade slapped on Korey Lee, whom they rank 4th.
