Rule 5 Draft Eligibility

1. A minor league player who was 18 or younger on the June 5th immediately prior to signing his first contract is eligible for selection starting with the 5th Rule 5 Draft after he signs, and a minor league player who was 19 years or older on the June 5th immediately prior to signing his first contract becomes eligible for selection starting with the 4th Rule 5 Draft that followed his signing.

2. If a player signs his first contract after the conclusion of the season of the MLB or minor league club to which he is first assigned, the next season is considered to be the player's "first season" for Rule 5 eligibility purposes.

3. A free-agent with prior MLB and/or minor league service who signs a minor league contract prior to the Rule 5 Draft is eligible for selection if the player was 18 or younger on the June 5th immediately prior to signing his first contract and it is at least the 5th Rule 5 Draft since he signed his first contract, or the player was 19 years or older on the June 5th immediately prior to signing his first contract and it is at least the 4th Rule 5 Draft since he signed his first contract. 

4. Any player on a minor league reserve list who has either been released or had his contract voided, and then re-signs with the same MLB organization within one year is eligible for selection. 

5. Any player on a minor league reserve list who has been outrighted to the minors previously in his career is eligible for selection. 

6. A player on the Voluntary Retired List, Disqualified List, or Ineligible List is not eligible for selection. 

7. An MLB club can designate any player on a minor league reserve list "eligible for selection" in the Rule 5 Draft even if the player would not normally be eligible, but once a player is designated eligible for selection, he remains eligible for selection in all subsequent Rule 5 drafts. However, a player who was signed after being selected in the First-Year Player Draft (MLB Rule 4 Draft) cannot be designated "eligible for selection" in a Rule 5 Draft until after the first anniversary of the player signing his first contract with an MLB organization.

8. A minor league player-manager who would be eligible for selection in the Rule 5 Draft if he was only a player can be selected, but if he is selected, the player-manager can reject the selection. He has 30 days to decide. If he rejects the selection, the player-manager cannot be re-signed as a player during the following season.
