Prior to the early 1990s this was not always the case, in some instances the "ATP Player of the Year" and the Year-end No. 1 in the rankings were different players. Novak Djokovic holds the ATP record of seven year-end No. 1 rankings. 18 players have achieved the year-end No. 1 ranking, four them (Lendl, Federer, Djokovic, Nadal) have done so in non-consecutive years. Six players have stayed at No. 1 in the ATP rankings every week of a calendar year. Connors and Federer have done so for three calendar years, Connors non-consecutively and Federer consecutively.
