Edmonds has been contemplating whether he'd return in 2011 after playing well (.276/.342/.504) in 86 games with the Brewers and Reds in 2010. Unsatisfied with contract offers after the 2008 season, he sat out all of 2009.
Despite Edmond's surprisingly solid effort in 2010, it's unlikely that his retirement will have much of a ripple effect on any rosters. He might only have gotten a minor-league deal this offseason, anyway, as he did last offseason from the Brewers.
If this is the end for Edmonds, it will have been a heck of a career. In 17 seasons, he's hit .284/.376/.527, claimed eight Gold Gloves and won a World Series with the Cardinals in 2006.
