ATLANTA — Flanked by his family, his former manager and a group of teammates he hates to leave behind, Chipper Jones choked up a bit and delivered the news that's been looming for years: It's time to call it a career. This time, he means it. With his 40th birthday approaching and a long string of injuries slowing him down, Jones announced Thursday he will retire after one more season as the Atlanta Braves' third baseman.
