Spanish teen sensation Carlos Alcaraz rose three places to sixth in the men's ATP rankings following his victory in the Madrid Open on Sunday.
The 19-year-old's 6-3, 6-1 trouncing of Germany's Alexander Zverev in Madrid was his fourth title of the year and rubber-stamped his chances of lifting his first Grand Slam in the upcoming French Open.
He had beaten his compatriot Rafael Nadal and Novak Djokovic on the way to the final.
The only worry for Alcaraz is a sore ankle which will see him miss this week's Rome tournament in order to be fit for the French Open which gets underway on May 22.
Djokovic retains his number one ranking - number two Daniil Medvedev is due to return to action at next week's Geneva Open after recovering from a hernia operation - while Australian Open champion Nadal remains at four.
Two players in the top 10 are on the slide as Italy's Wimbledon finalist Matteo Berrettini, who has yet to play on clay this season as he recovers from an operation on his right hand, drops two spots to eighth and Norwegian Casper Ruud slips to 10th from seventh.
South Africa's Lloyd Harris, who lost 6-3, 3-6, 6-7 (7/9) to Russian Aslan Karatsev in the Italian Open first round on Sunday, moved up two spots to No 36 in the world.
Karatsev saved a match point in the deciding set tie-break to defeat Harris and book a second-round clash with world No 1 Novak Djokovic.
