Our 2018 Prospect Rankings Guidelines

1. Players who have exceeded rookie qualifications (130 AB, 50 IP) are not included.

2. Our list includes some players that are currently in the major leagues, but with short tenures. Many of those players will probably be purged from the list as soon as we become more confident that they're not in danger of being sent back down to the minors.

3. This list tilts more toward fantasy potential than MLB potential.

4. It takes positional history into account.

5. It gives those who have played in full-season leagues preference over players with only short-season league history and discount recent draftees that have not yet played in the minors.

6. Unsigned import players are not ranked here.

7. College players are not considered prospects until they are signed with their major league organization and start producing in the minors.

8. Relievers are unlikely to appear as top prospects because nearly all of them need to fail as starting prospects first.
