Nadal regained the number one ranking in September from Novak Djokovic of Serbia and finished the year with more ATP Tour rankings points than would number three David Ferrer of Spain and world number four Andy Murray of Great Britain combined.

Williams last year enjoyed one of her most successful years on the WTA Tour ever as she rebounded from an ankle injury at January’s 2013 Australian Open to win the French Open and the US Open. In October Williams regained the WTA Tour’s number one ranking once again after first reaching the top ranking in July of 2002 at age 20.
