Former world number one, Novak Djokovic has slipped out of the top four after the new list published by the ATP on Monday.
The Serbian, who recently announced that he would be taking a break from competitive tennis to rest a niggling elbow injury, has now been replaced by US Open champion, Stan Wamrinka.
Djokovic is now ranked fifth, a move that comes after last year’s points for winning the Montreal Masters came off the rolling 12-month system.
Andy Murray remains as the world number one, though his position is expected to come under threat from Rafael Nadal and Roger Federer, who returned to the top three, with the US Open fast approaching.
However, Roger Federer returned to the top three after capturing a record-breaking eighth title at Wimbledon, to break back into the Top 3 of the Emirates ATP Rankings for the first time since 15 August 2016.
With a straight sets win over Marin Cilic in the final, it marked his fifth tour-level title of the season and his 19th Grand Slam championship crown.
It was Federer’s second major title without dropping a set (also 2008 Australian Open) and moves him firmly into contention for year-end No. 1 honours.
The ATP also announced today that Federer has qualified for a record 15th time for the Nitto ATP Finals, to be held at The O2 in London from 12-19 November.
