Chicago Cubs President of Baseball Operations Theo Epstein topped Fortune Magazine's annual list of the world's 50 greatest leaders.
Epstein, 43, was cited by the magazine as the "wunderkind executive who realized he would need to grow as a leader in order to replicate in Chicago the success he’d had with the Boston Red Sox."
In 2004, at age 28, Epstein became the youngest general manager in the history of Major League Basball when he was hired by the Red Sox.
The Red Sox went on to win the World Series in 2004, breaking an 86-year drought without a title.
