BRONCO 12U™ LEAGUE is a continuation of the philosophy to fit the diamond to the physical potential of the players.

The bases and pitching distances are scaled up slightly from MUSTANG 10U™ LEAGUE.

The transition diamond used in BRONCO 12U™ LEAGUE permits infielders and outfielders to select their defensive positions in relationship to the anticipated speed of the ball when they field it.

Without this transition diamond, BRONCO 12U™ LEAGUE players play their position disproportionately closer to the bases, infield and pitcher.

This diamond positions the infielders and outfielders in direct proportion to that assumed by Major League Baseball players and Professional Girls Softball players and permits the younger players to play the game as it was designed to play.
