At 28 years old, Theo Epstein was the youngest general manager in baseball history when he took over the Red Sox before the 2003 season.

A lot of great things happened to the Sox while Epstein was general manager. The team won two World Series, made the playoffs six times, and averaged more than 94 wins per season. Scouting and player development improved dramatically, and the Sox won that second championship with home-grown talents Dustin Pedroia, Jon Lester, Jonathan Papelbon, and Jacoby Ellsbury leading the way.
