Ricketts is also on the board of directors of the Chicago Cubs. In April 2007, Sam Zell announced his intention to acquire the Chicago-based Tribune Company. After acquiring the Tribune, Zell announced that he would sell the Cubs and related entities including Wrigley Field and a 25% share of SportsNet Chicago. The Ricketts family bid was selected as the winning bid on January 22, 2009. The family bid included all four siblings (Peter, Tom, Laura, and Todd) and both parents. "Forbes" estimated that the ownership stake in the Chicago Cubs represents $642 million out of the total $900 million bid. Ricketts has a World Series title to his credit, as the Cubs won the championship in 2016 defeating the Cleveland Indians four games to three.
