Samantha Stosur ascended to her career-high ranking of No.10 on March 22, fell out of the Top 10 two weeks later, but now is back in the Top 10 again on the latest Sony Ericsson WTA Tour Rankings.

Stosur went from No.11 to No.10, switching places with Kim Clijsters following her victory in Charleston. She could establish a new career-high with a strong performance in the coming weeks at Rome (if she plays there) and Madrid, as she lost early in those events in 2009. Not a great clay courter early in her career, Stosur has improved on the dirt significantly. She was 34-35 before 2008, but since then is 18-8 on clay, including 10-1 in her last 11 matches.

The Australian's victim in Sunday's Family Circle Cup final, Vera Zvonareva, jumped back into the Top 20 after a month ranked outside the Top 20 - going from No.22 to No.19. The Russian has a great chance to ascend much more, as she missed the entire European clay court season last year after suffering a right ankle injury in Charleston, therefore has no points to defend for a while.

Charleston quarterfinalist Melanie Oudin established a new career-high for the third straight week, rising from No.36 to No.31. Also reaching new career-highs were Barcelona semifinalists Yaroslava Shvedova and Alexandra Dulgheru. Shvedova moved from No.42 to No.35 and Dulgheru from No.51 to No.45.

Another player making noise was Alicia Molik, who climbed from No.101 to No.97, cracking the Top 100 for the first time since returning to action last summer following about a year-long absence. She previously spent a total of 339 weeks in the Top 100.
