The Cardinals signed All-Star second baseman Matt Carpenter to a six-year, $52 million extension on March 6, 2014. Included was an option for 2020 worth $18.5 million. The year prior, he led the major leagues in hits, runs scored, and doubles while batting .318 and becoming a regular at a position he had yet to play as professional. Mozeliak cited his work ethic as another factor in the extension.
