Fox spent more than 50 years working for the Minnesota Twins/Washington Senators organization, and began his career as the general manager of a Senators' Minor League affiliate in the late 1940s. In the early '50s, he joined the Major League team, first working in the public relations department before becoming the team's traveling secretary, a role that he held when the team moved to Minnesota.
Fox became club president in 1984 and was a part of the change in management that led to the Twins' World Series championship in '87. He also was a member of the Twins' executive board and threw out a ceremonial first pitch at Target Field last season as part of the organization's 50th anniversary celebration in early September.
"The Minnesota Twins organization is deeply saddened by the passing of our great friend and a longtime steward of the ballclub -- Howard Fox," Twins executive board chairman Jerry Bell said in a statement.
"Howard's talents, leadership and passion for the game of baseball were quite instrumental in the long-term success of the Twins organization. Today we celebrate Howard's legacy while sharing our thoughts and prayers with Yvonne and the entire Fox family."
Funeral arrangements for Fox are pending.
