His Cardinals won more than 100 games four times: the 1931 world champions, and then the juggernaut 1942–43–44 teams of the World War II era that won 106, 105 and 105 games in consecutive years, along with their three NL pennants and two World Series championships. The 1942 Cardinals were the only National League champion to ever defeat Joe McCarthy's Yankees in a Fall Classic, taking the series four games to one. That season marked the last year of the Breadon-Rickey tandem; their relationship had begun to fray during the late 1930s, when Breadon sold his automobile dealerships and became more involved in his baseball team, and Commissioner of Baseball Kenesaw Mountain Landis cracked down on Rickey's farm system, making 74 players free agents. With Rickey's contract as general manager set to expire at the end of October 1942, Breadon notified him that he would have to take a cut in pay. Instead, Rickey moved to the Brooklyn Dodgers, where he would make history as the club's president and top baseball executive.
