The Yankees have added the following players to the 40 man roster in preparation for the Rule Five draft in Dec. RHP Hector Noesi RHP Ivan Nova RHP Romulo Sanchez INF Reegie Corona INF Eduardo Nunez INF Kevin Russo OF Austin Jackson In order to make room on the 40 man roster Shelly Duncan was outrighted to Scranton Wilksbarre.  For those of you that don’t know how the rule five draft works here is the Wikipedia definition : As in the amateur draft, the selection order of the teams is based on each team’s win-loss record from the prior regular season, each round starting with the team with the worst record and proceeding in order to the team with the best record. Any player selected under Rule 5 is immediately added to his new team’s 40-man roster; thus, teams who do not have an available roster spot may not participate in the Rule 5 draft. Players who are not currently on their team’s 40-man roster are eligible to be selected in the Rule 5 draft, but only after a standard exemption period has elapsed. See Selection eligibility below. If chosen in the Rule 5 draft, a player must be kept on the selecting team’s 25-man major league roster for the entire season after the draft—he may not be optioned or designated to the minors. The selecting team may, at any time, waive the Rule 5 draftee. If a Rule 5 draftee clears waivers by not signing with a new MLB team, he must be offered back to the original team, effectively canceling the Rule 5 draft choice. Once a Rule 5 draftee spends an entire season on his new team’s 25-man roster, his status reverts to normal and he may be optioned or designated for assignment. To prevent the abuse of the Rule 5 draft, the rule also states that the draftee must be active for at least 90 days. This keeps teams from drafting players, then placing them on the disabled list for the majority of the season. For example, if a Rule 5 draftee was only active for 67 days in his first season with his new club, he must be active for an additional 23 games in his second season to satisfy the Rule 5 requirements. Any player chosen in the Rule 5 draft may be traded to any team while under the Rule 5 restrictions, but the restrictions transfer to the new team. If the new team does not want to keep the player on its 25-man roster for the season, he must be offered back to the team of which he was a member when chosen in the draft The Purpose of the Rule five draft is to keep teams from stockpiling young talent. However its a risk for any team that decides to pick up a player being that they have to keep them on the 25 man roster for the entire season.Players are eligible for selection in the Rule 5 draft who are not on their major league organization’s forty man roster and: – were signed at age 19 or older and have been in the organization for four years; or – were signed at age 18 or younger and have been in the organization for five years. I believe that  Shelly Duncan although removed from the 40 man roster has only been with the organization for three years therefore cannot be selected by another team as a rule five draftee. This is why they were able to move him off the roster to make room for the players they needed to protect without losing him.
