The World Straight Pool Championship is a pool competition, that was held up until the game of Nine-ball became popularized in America. It was the most prestigious straight pool tournament up until the early 21st century, tournaments like the American 14.1 Straight Pool Championship and the European Pool Championship 14.1 that are still held annually, have gained prominence in recent years. During the tournament's early years, it was the only global professional title for straight pool (also known as 14.1 continuous). The event was revived in 2006, in part to restore the game's popularity in the United States.[1] The World Straight Pool Championship was sanctioned by the World Pool-Billiard Association (WPA) in 2006, 2007, 2008, and 2010.[2] The tournament continued unsanctioned from 2011 to 2019. Ralph Greenleaf & Willie Mosconi are the most successful players having both won the tournament on 19 occasions. The oldest player to win the tournament is Irving Crane at 59 years old at the time of his victory. The youngest player to win the tournament is Ralph Greenleaf at 20 years old at the time of his first victory.
