The world snooker rankings are the official ranking system for professional snooker players. They determine who qualifies automatically for World Snooker Tour tournaments. The World Professional Billiards and Snooker Association maintains these rankings. They not only give players an idea about their ranking but also provide useful statistics about the sport.
Judd Trump
Judd Trump is among the top ten in world snooker rankings. He is known for his amazing breaks and his dominance of the sport. He has won 23 rankings titles, including the World Championship. He is only 33 years old and still has the potential to remain at the top of his sport for at most ten more decades. However, his age combined with the grind of the tour might wear him down.
Mark Selby
The Englishman Mark Selby is one of the best players in the world. He is an English Under-15 champion, and a recent World Snooker Championship champ. He has also a background in pool. He was the 2006 WEPF Eight-Ball Pool Champion and a finalist in 2015's Chinese Pool World Championship. Selby is originally from Leicester, England.
