Paris - Spain's Rafael Nadal maintained his hold on top spot in the men's ATP Tour rankings on Monday after his 11th French Open success.
The Spaniard is 100 points ahead of Roger Federer going into the grasscourt season where the Swiss will be looking to close the gap.
Beaten finalist Dominic Thiem of Austria rose one spot to seventh.
Germany's Alexander Zverev remains third after reaching the quarters in Paris with Argentine semi-finalist Juan Martin Del Potro up two places to fourth.
The big mover in the top echelons of the men's game is Italian surprise package Marco Cecchinato, who had never won a Grand Slam encounter before barrelling his way to the last four at Roland Garros.
He rises 45 spots to 27th after becoming the first Italian man to reach the last four of a major in 40 years.
