Biggest Retirements of 2010

One of two managers with six 100-win seasons, Atlanta's venerable Bobby Cox has said 2010 will be his last season as a manager. He led the Braves to the 1995 World Series title and guided Atlanta to a record 14 consecutive division titles, from 1991 to 2005. The four-time manager of the year also oversaw the Toronto Blue Jays for four seasons, beginning in 1982.
