Cardinals starting pitcher Chris Carpenter is calling it a career. The right-hander is officially retiring. General manager John Mozeliak revealed the news at a Wednesday press conference. The 2005 Cy Young winner missed most of the 2012 season and all of 2013 due to injury. The 38-year-old helped the Cards to World Series championships in 2006 and 2011. In 15 seasons, Carpenter had 144 wins with a career ERA of 3.76 while pitching for Toronto and St. Louis.
