12/12 UPDATE: The Arizona Diamondbacks selected RHP Marcos Mateo from the Cubs AAA Iowa affiliate with the 15th overall selection in the first round of the Major League Phase iof the 2013 Rule 5 Draft. Because he has been outrighted previously in his career, Mateo can elect free-agency if he is later re-claimed by the Cubs. (If re-claimed, a player selected in the Major League Phase of the Rule 5 Draft MUST be sent outright to the minor league club from which he was drafted).
The Cubs also lost 1B Justin Bour (to Miami), OF Julio Borbon (to Baltimore), and RHP A. J. Morris (to Pittsburgh) off the AA Tennessee roster in the AAA Phase. Once selected, players chosen in the AAA or AA Phase cannot be re-claimed.
The Cubs did not make any selections in the Major League Phase of today's draft, but they did select left-handed hitting catcher Charlie Cutler from the Pittsburgh Pirates AA Altoona roster in the AAA Phase. Cutler was a college teammate of Cubs OF Brett Jackson at Cal.
