Some members of the Seattle Mariners front office will not be returning, but new general manager Jerry Dipoto is retaining several key members of the organization.

Assistant general manager Jeff Kingston, amateur scouting director Tom McNamara and pro scouting director Tom Allison will remain on with the Mariners.

Also remaining on will be two special assistants to the general manager -- Roger Hansen and Ken Madeja -- and international operations director Tim Kissner.

Chris Gwynn, the director of player development, resigned last week and five other front-office members -- special assistants to the GM Ted Simmons, Joe McIlvaine and Pete Vuckovich and pro scouts Joe Nigro and Duane Shaffer -- were informed their contracts would not be renewed on Nov. 1.
