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. Any 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, as long as 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 in the Rule 5 Draft, but a player on the Restricted List or the Military List is 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 made 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.

NOTE: Juan Carlos Paniagua signed his first contract with the Arizona Diamondbacks as "Juan Callado" on 5-8-2009 and pitched for the DSL Diamondbacks in the Dominican Summer League in 2009-10, but the contract was "pending" for almost two years and was never officially approved by MLB. The contract was eventually rejected by MLB due to "fraudulent paperwork" and Paniagua (Callado) was suspended for one year and then was declared a free-agent. He signed with the New York Yankees in March 2011 but then was suspended again and that contract was rejected, too, because his birth certificate could not be verified. Paniagua was cleared by MLB in 2012 and he signed with the Cubs on 7-9-2012. Therefore, Paniagua could be eligible for selection in the Rule 5 Draft for the first time in December 2013, since 2009 was his "first season" on the field, and he was 18 on the June 5th immediately preceding the signing of his first contract, or he might not be eligible for selection in the Rule 5 Draft for the first time until December 2015 if 2012 is considered Paniagua's "first season" for Rule 5 eligibility purposes.
