The BCA Pool League (BCAPL) is one of the major amateur pool leagues in the United States and is present in over a dozen other countries outside the U.S., with a significant presence in Canada.

CSI is owned by billiards promoter and 2009 Billiards Digest "Man of the Year" Mark Griffin.
The BCA Pool League has approximately 450 local leagues with 60,000+ members. Leagues are played on both bar-size 7- foot (2.1 m) and regulation 9- foot (2.7 m) tables. The BCAPL National 8-Ball Championships held every May in Las Vegas, Nevada billed itself, "The Greatest Pool Tournament in the World", with 22 separate divisions including singles, scotch doubles , teams. The event also hosts two professional tournaments.
