In 2009, Chesterfield Baseball Clubs (CBC), along with PONY Baseball, wanted to start an event to spotlight the abilities of 11-year-old players at the highest level, and the Bronco-11 World Series (B11WS) was born. The B11WS is a world-class international youth baseball tournament involving the best 11-year-old PONY Baseball teams from around the world.

Annually, the B11WS consists of three international teams from Mexico, the Caribbean, and Asia, as well as four U.S. teams and host Chesterfield. Fans attending the eight-team tournament have witnessed teams from Mexico, California, Florida, Illinois, and even host Chesterfield bring home a championship title over the years.

The Bronco 11U World Series is now entering its 14th year in Chesterfield, Virginia, and, for over a decade, the Bronco 11U World Series has been a staple for baseball in Central Virginia.
