Joe Torre announced today that he was retiring as manager of the struggling LA Dodgers. The team immediately named former Yankee and current hitting coach Don Mattingly as his replacement. Torre has managed the Dodgers since the 2008 season, and coached the Yankees to four World Series titles in 12 years as their head coach. Torre turned 70 in July and has a 2,318-1,990 regular-season record in 29 major league seasons as a manager. Mattingly was the bench coach with the Yankees in 2007, and hoped to replace Torre as manager, but lost out to Joe Girardi; instead, he followed Torre to LA, as his heir apparent. It's unclear currently whether Torre is retiring from managing entirely or not.
