1989–90 snooker world rankings

The World Professional Billiards and Snooker Association (WPBSA), the governing body for professional snooker, first introduced a ranking system for professional players in 1976, with the aim of seeding players for the World Snooker Championship. The reigning champion would be automatically seeded first, the losing finalist from the previous year seeded second, and the other seedings based on the ranking list. Initially, the rankings were based on performances in the preceding three world championships. The 1983–84 snooker world rankings were the first to take tournaments other than world championship into account, and several additional tournaments were designated as ranking tournaments over the following years. The list for the 1986–87 snooker season was the first to only take account of results over two seasons, and the rankings for 1989–90 were also based on results from the preceding two seasons. Barry Hearn, the manager of a number of leading players including Steve Davis and Jimmy White, made a proposal to the WPBSA to change the system so that only the best seven performances from the ten ranking tournaments were counted. It was rejected at an extraordinary meeting of the WPBSA in May 1989.
