Cape Town - For the first time in 13 years, Roger Federer and Rafael Nadal are both ranked outside the top four in the men's world rankings.
For well over a decade, the duo have dominated the tennis landscape and been permanent fixtures right at the top of the men's game, but the latest list sees Nadal now occupy fifth place, with Federer two places lower.
Nadal, 30, has won two tournaments this season - in Barcelona and Monte Carlo - but that's a much less impressive return that he's been accustomed to.
Thirty-five-year-old Federer, meanwhile, has seen his 2016 campaign disrupted by injury. The Swiss has been on the sidelines since Wimbledon but is targeting a return in January.
Don't fret, though, Nadal and Federer fans, as neither man is contemplating retirement at this stage. Expect them to keep fighting in the new year.
Serbia's Novak Djokovic, who is the current dominant force in the men's game, retains his place at the top of the ATP standings.
Scotland's Andy Murray follows in second place, followed by Stan Wawrinka - both Grand Slam champions in 2016.
Japan's Kei Nishikori lies in fourth spot, his highest ever ranking.
