Rafael Nadal returned to No. 4in the world in the latest ATP rankings this week, but the biggest mover on the boards was France's Benoit Paire, who soared 10 spots to No. 26 in the world following his trip to the semifinals at Rome that saw him defeat three players ranked higher than him including No. 7 Juan Martin Del Potro.
The 24-year-old Paire was just 14-14 before the tournament began last week. His ascension gives France five players ranked in the Top 30, the most of any country.
Nadal's title at Rome ends David Ferrer's reign of seven consecutive and 14 of the past 15 weeks as the No. 1 ranked Spaniard.
In another Top 10 move, Janko Tipsarevic moved back to No. 10 in the world, a mere 10 points ahead of Stanislas Wawrinka.
Andy Murray's announcement that he will not compete in the French Open means he will lose 360 points off his ranking after making the quarterfinals at Roland Garros last year. This means that if No.3  Roger Federer can reach the tournament final, he would retake the No. 2 position from the Scot.

There was plenty of shuffling in the women's Top 10, with Italy's Sara Errani rising to No. 5 in the world, a new career high. Errani is the first woman to be ranked in the top 5 simultaneously in singles and doubles since Serena Williams accomplished the feat shortly before her season-ending injury in 2010.
Errani jumped Na Li, who fell to No. 6, just in front of Petra Kvitova, the new No. 7, passing Angelique Kerber. Samantha Stosur retook No. 9 from Caroline Wozniacki.
