In 2000, Mincher was named interim president of the Southern League, where the Stars play, when league president Arnold Fielkow left for an executive position with the New Orleans Saints of the National Football League. Mincher resigned from his position with the Stars when his group sold the team to Miles Prentice in early 2001. This cleared the way for the Southern League to remove the interim tag and they made him league president beginning with the 2001 season. He served as league president until retiring in October 2011, at which point the league named him President-Emeritus.
