In March 2014, the Redbirds were purchased by their major league parent club, the St. Louis Cardinals. The transaction also included the City of Memphis acquiring AutoZone Park and then leasing it to the team. Ron Warner led his club to a first-place finish (79–64), clinching the American Conference South. They were defeated in the conference series, three games to one, by Omaha, who later won the PCL title. The 2015 club, under manager Mike Shildt, finished in second place (73–71), two games behind the Round Rock Express.
