In one of the wildest weeks the ATP rankings have ever seen, every player from No. 4 to No. 25 moved at least one spot following the Sony Ericsson Open in Miami.

The three men at the top did not, but No. 2 Novak Djokovic continued chipping away at the lead of No. 1 Rafael Nadal.  Thanks to Djokovic's win over Nadal in the tournament final on Sunday, the Spaniard's points lead over the Serb dropped from 2,230 to 1,560.

Stanislas Wawrinka remained No. 3 ,but that's where the similarities ended. Roger Federer moved up to No. 4 in  the world, with Tomas Berdych fifth while David Ferrer dropped two spots to sixth.
It marks the 527th week that Federer has been ranked int he Top 4 in the world - second only in ATP history to Jimmy Connors (669).

Andy Murray fell two spots to No. 8, his lowest ranking since he was ninth in the world in July of 2008, while American John Isner climbed to a career-best tying ninth, with Milos Raonic of Canada rejoining the elite at No. 10 behind him.
Frenchman Richard Gasquet fell out of the Top 10 altogether, down two spots to No. 11.
