Nashville SC announced the signing of defender Robert Castellanos on Wednesday. The 22-year-old Castellanos is viewed as a player with promise by the second-year MLS squad. "Robert has the tools to be a contributor at this level and has gained some valuable experiences already at a very early stage of his playing career," Nashville general manager Mike Jacobs said in a statement. "He will be able to add to the depth of our back line."
