Aaron Boone officially announced his retirement on Tuesday, while also accepting a position as an analyst with ESPN. Boone will debut as part of ESPN's "Baseball Tonight" panel starting in March. He also will make select appearances on ESPN as a game analyst. "It is with a sense of pride, sadness, and enthusiasm that I formally announce my retirement after 16 years of professional baseball," Boone said. "It has been a privilege and honor to have played in the major leagues for 12 seasons for six different clubs. "While it's tough to leave the game as a player, I am eager to start my next career with my new team at ESPN. I am very grateful that I'll be able to stay in the game as an ESPN analyst and work with people who share the same passion for baseball that I do."
