2009 United States Bowling Congress Open Championships

With nearly 15,000 teams already registered, the 2009 United States Bowling Congress Open Championships slated for Las Vegas' Cashman Center may become the largest tournament held outside of Reno, Nev., and that number will continue to grow following the decision to add more lanes to the tournament venue.

Instead of 56-lanes and a capacity of 16,300 teams as planned, the 2009 USBC Open Championships will feature 60-lanes and be able to accommodate 17,400 teams, which could make it the largest tournament in history. The participation record of 17,285 teams was set when the National Bowling Stadium in Reno opened its doors in 1995. The largest event outside of Reno was the 2005 tournament in Baton Rouge, La., which featured 13,222 teams.
