Robert Joe Cox (born May 21, 1941) is an American former professional baseball third baseman and manager in Major League Baseball (MLB). He first led the Atlanta Braves from 1978 to 1981, and then managed the Toronto Blue Jays from 1982 to 1985. He later rejoined the Braves in 1986 as a general manager. He moved back to the manager’s role during the 1990 season and stayed there until his retirement following the 2010 season. The Atlanta Braves have since retired the number 6 in commemoration of Bobby Cox. He led the Atlanta Braves to the World Series championship in 1995. He holds the all-time record for ejections in Major League Baseball with 158 (plus an additional three post-season ejections), a record previously held by John McGraw.
Cox ranks fourth on the baseball all-time managerial wins list.
