Novak Djokovic is no longer a member of tennis' big four after slipping down to fifth place in the latest ATP world rankings.
The 30-year-old Serbian recently confirmed that his 2017 season is now over as he has been struggling with an elbow injury for some time and the final straw appears to have been when he was forced to pull out of Wimbledon at the quarter-final stage.
Djokovic will also miss the US Open at the end of August so he will also definitely end the season without a Grand Slam title.
With five more months remaining in 2017, Djokovic is likely to find himself further down the rankings, but Stanislas Wawrinka is the man who has taken over his place in fourth position at this moment in time.
Andy Murray continues to hang on to his place at the top of the rankings, while Rafael Nadal is second and Wimbledon champions Roger Federer is third.
Germany's Alexander Zverev reward for an impressive campaign is a career-high eighth position, while Argentinian Leonardo Mayer's Hamburg Open win has resulted in him jumping up a massive 89 places to 49th.
