World Tenpin Bowling Association Patterns
Team USA Experience
Effective November 1, 2010, USBC no longer has the right to offer Sport Bowling leagues that use PBA patterns or trademarks.
As a Sport Bowling alternative to PBA Experience leagues, USBC will offer Team USA Experience leagues. Rather than the PBA patterns, the Team USA Experience leagues feature the 12 World Tenpin Bowling Association, Sport compliant patterns Team USA competes on internationally.
