Spearheaded by Andy Murray's ascension to No. 2 in the world, the ATP top 10 rankings saw their most movement in more than a year on Monday.
Murray, winner of the Miami Sony Ericsson Open, bypassed new No. 3 Roger Federer by 80 points. Miami finalist David Ferrer similarly jumped former Rafael Nadal to reclaim No. 4 by a wide margin, close to 700 points.
At the tail end of the Top 10, France's Richard Gasquet, a Miami semifinalist, nudged ahead of Janko Tipsarevic by 230 points.
The 25-year-old Murray is off to a 19-2 start in 2013 with two titles and nearly $2.2 million in earnings. This is his first week at No. 2 since August 31, 2009, the last of three weeks he was ranked at the penultimate spot.
Federer slips back to No. 3 for the first time since July 2, 2012, just before he won Wimbledon to jump to No. 1.
Outside the Top 10, the biggest move came courtesy Miami semifinalist Tommy Haas. Haas, who turns 35 this week, rose four spots to No. 14, his highest spot since January of 2008 when he was ranked 11th.
Sliding the other way was Argentina's Juan Monaco, who dropped five spots to No. 19. Oft-injured American Mardy Fish fell even further, down nine spots to No. 42. Fish has played just two matches this year.
Serbia's Novak Djokovic leads Murray by 3,620 points for the No. 1 spot. It's Djokovic's 22nd straight week at No. 1 and 75th overall. The 75 weeks at No. 1 for Djokovic is the 10th-most weeks at No. 1 in ATP history. With six more weeks at No. 1, Djokovic will pass Lleyton Hewitt for the ninth-most weeks holding the top spot.
WTA
There was only one change in the women's Top 10 after Miami - Samantha Stosur moved ahead of Caroline Wozniacki to take over the No. 9 position in the world. Stosur is only 8-7 on the year, but Wozniacki lost points by tumbling in the third round at Miami a year after reaching the semifinals there.
Spots 11-20 wee a huge jumble, however, with only three players keeping the same slots they held a week ago.
Nadia Petrova moved up to No. 11, Maria Kirilenko to No. 12 and Roberta Vinci to No. 13. Former No. 1 Jelena Jankovic lept from 24th to 18th after reaching the Miami semifinals. It was Jankovic's best performance at Miami since she reached the final in 2008 while ranked No. 3 in the world.
With her win over Maria Sharapova in the Miami final, Serena Williams maintained a lead of 1,100 points for the No. 1 spot in the world. Williams has now been ranked No. 1 in the world for 130 weeks in her career.
