"Andy is a very capable goalkeeper, someone who has been successful in Major League Soccer and has had a lot of games in the league," Sporting KC head coach Peter Vermes said.
"He is a great addition to our team and a complement to our goalkeepers. We needed someone with a lot of experience because we're in multiple major competitions in 2014."
The Kansas native, who made 82 MLS appearances for the Crew, added: "I could not be more excited to come back home and play in front of family and friends.
"The ownership, coaching staff, players and fans associated with Sporting KC are first class, and I look forward to working with two amazing goalkeepers to help win another championship. I would like to thank Peter and the rest of the organization for giving me this opportunity. My wife and I are ecstatic to be able to call Kansas City home once again."
