The St. Louis Cardinals signed manager Mike Matheny to a three-year contract extension through the 2020 season on Thursday.
Financial terms were not disclosed by the team for Matheny, who guided St. Louis to the World Series against the Boston Red Sox during his second season after taking over for longtime skipper Tony LaRussa. The 46-year-old Matheny won three consecutive National League Central titles (2013-15) during his five seasons as manager.
