For the first time in 13 years, neither Roger Federer or Rafael Nadal occupy one of the top four spots in the latest ATP standings, signalling the end of an illustrious era.
Both have dominated the tennis scene for well over a decade, with their rivalry considered the most prominent and fierce in the history of the sport.
The pair held the top two spots for four consecutive years from July 2005 to August 2009, making them the only duo to have achieved that feat.

They have played each other 34 times in all competitions and 11 times during Grand Slams, with Nadal leading Federer 23-11 and 9-2 in both categories respectively.
A staggering 21 out of their 34 matches have been in tournament finals, with eight being Grand Slam finals, an all-time record.
Having dominated the stage for over a decade, their rivalry is one of the most prominent in sporting history, bringing a high level of tennis to fans around the world.
Their 2008 Wimbledon final is hailed as the greatest match in the sport's history by many analysts.
Along with Andy Murray and Novak Djokovic, Federer and Nadal formed the so-called "Big Four" of tennis, with the quartet having enjoyed the top four spots from 2008 to 2013.
However, only Murray and Djokovic remain in the top two out of the quartet, with Nadal slipping down to fifth, and Federer down in seventh.
This period is widely considered the "Golden Era" of tennis as all four competitors are capable of seriously contending for any major tournament.
Djokovic is currently the world number one, with reigning Wimbledon champion Murray following in second spot.
Swiss player, Stan Wawrinka occupies third spot, while Japan's Kei Nishikori sits in fourth place.
Nadal, who last won a Grand Slam in 2014 in the form of the French Open, has been repeatedly plagued with niggling injuries, with back and wrist injuries proving to be the most costly.
The Spaniard has, therefore, been unable to put together a string of notable tournament appearances in recent times, forcing him to take a backseat.
Federer, now a veteran, is simply past his peak, and despite his existing tennis playing prowess, younger and more energetic players have now taken over the courts.
The 25-year-old last won a Grand Slam in 2012, where he defeated Murray in the finals of Wimbledon after knocking out defending champion Djokovic in the semis.
The Swiss has, since then, suffered a decline in form and fitness, which is understandable at this stage of career.
