Stan Wawrinka has climbed back into the ATP rankings' top five thanks to his French Open triumph, but Rafael Nadal's struggles at Roland Garros have dropped him to 10th.
The Swiss sealed his second major title courtesy of a 4-6 6-4 6-3 6-4 win over Novak Djokovic on Sunday, denying the world number one the career Grand Slam.
Wawrinka dropped from fourth in the rankings to ninth in February, but his moment to savour at Roland Garros has him back among the sport's elite.
The deposed 'King of Clay' Nadal saw his hopes of a 10th Paris title go up in smoke at the quarter-final stage against Djokovic, dropping him to a 10-year low ranking, dating back to when he was just 18 years old.
Nadal now heads to the grass-court season, where his ranking could be hit further. The Spaniard's progression to the fourth round at last year's Wimbledon was a three-year best at the All-England Club.
Another player whose star has fallen in recent months is Eugenie Bouchard. The Canadian has endured a miserable 2015 thus far and is out of the WTA top 10 after a first-round French Open defeat to Carla Suarez Navarro, slipping to 11th.
Petra Kvitova is on the up, however, climbing to second in the rankings, though predictably still well short of French Open champion Serena Williams – who tightened her grip on top spot with a 20th career major success.
Her final opponent in Paris, Lucie Safarova, is in the top 10 for the first time after her impressive run on the clay, having reached seventh.
