Monte Carlo was fine and dandy for Spaniards Rafael Nadal (the champ) and David Ferrer (runner-up) on Sunday, but the same couldn't be said for countryman Fernando Verdasco—who plummeted four spots and fell out of the top 10 for the first time since April 4, 2010.
A finalist in Monte Carlo a year ago, Verdasco fell in the second round this year. His drop allowed four players to move up one spot each, including American Mardy Fish, who moved into the top 10 at No. 10 for the first time in his career.
Ahead of him, Jurgen Melzer moved up to a career-best No. 8, and Gael Monfils moved to ninth, his highest spot since April 27, 2009.
Further down the list, the Ukraine's Alexandr Dolgopolov joined the top 20 (at No. 20) for the first time in his career, moving up one spot. Richard Gasquet took over as the top Frenchman in the world, moving up to 17th, while former top-10 player Jo-Wilfried Tsonga fell to 18th.
Dolgopolov's fellow young gun Milos Raonic took another leap forward as well, six spots to No. 28. Raonic fell early in the tournament, but every main field he makes this season is another chance for points considering he was almost exclusively a Challenger player last year.
One of those he passed was American John Isner, who fell to 29th after being ranked as high as 19th just four months ago.
Joining Raonic with a big jump up was Ivan Ljubicic, who leapt seven spots to 33rd thanks to his appearance in the quarterfinals.
Surprise quarterfinalist Frederico Gil made one of the biggest moves inside the top 100, vaulting 18 spots to No. 64, easily his career best.
Joining the top 100 for the first time is American Donald Young, who soared 24 spots to No. 98 after winning the Tallahassee Challenger.
There was only one change in the women's top 10, as Na Li surpassed Samantha Stosur to take over No. 6 in the world. Li is at 4,300 points and now within striking distance of the top five.
