We mourn the passing of Hall of Famer Bobby Cox, the fourth-winningest manager in MLB history. Cox led the Atlanta Braves to unprecedented success, winning 14 straight division titles from 1991-2005, along with 5 NL pennants and the 1995 World Series championship. The four-time Manager of the Year won 2,401 games overall, behind only Connie Mack, Tony La Russa, and John McGraw. Of the 13 managers with at least 2,000 career wins, only one (Joe McCarthy) got there in fewer games than Cox. Cox managed the Braves for 25 seasons in all, leading them to six 100-win seasons and eight 90-win seasons. He also managed the Blue Jays for four years, including the franchise’s first winning record in 1983 and first division title in 1985. As General Manager of the Braves from 1986-90, Cox laid the foundation for the teams he would manage to success over the next two decades by trading for one future Hall of Famer in John Smoltz, drafting another in Chipper Jones, and helping develop homegrown legend Tom Glavine. Owner of a .556 winning percentage in 29 total seasons as manager, Cox was elected to the Hall of Fame in 2014. He was 84 years old.
