The Cubs have officially announced the signing of 13 of their 41 selections in the 2017 MLB First-Year Player Draft (MLB Rule 4 Draft).
Players selected in the MLB First-Year Player Draft (MLB Rule 4 Draft) are placed on a club's Negotiation List.
In most cases, a player selected by a club in the Rule 4 Draft will remain on the club's Negotiation List until either the player signs or until 5:00 PM (EDT) on the Friday that falls during the week July 12-18 (whichever comes first), and if a club does not sign a Rule 4 Draft pick by the deadline, the player is removed from the club's Negotiation List and becomes eligible for selection again in the next Rule 4 Draft in which the player would be eligible for selection.
