PARIS: Novak Djokovic dropped one place to fifth with Stanislas Wawrinka moving up to fourth in the ATP rankings published on Monday.
Former world number one Djokovic will likely fall further by the end of the year as he has already announced he will not play again this season due to an elbow injury.
The main move saw German Alexander Zverev climb three places to a career high eighth.
Argentina's Leonardo Mayer was the biggest mover, up 89 places to 49th following his victory in the Hamburg Open.
And there was consolation for German beaten finalist Florian Mayer, who still moved up 45 spots to 56th.
Britain Andy Murray remains top ahead of Rafael Nadal with Roger Federer third.
