In Monday's new rankings, Federer jumps from No. 3 to the top, overtaking Novak Djokovic and Rafael Nadal. Federer last was No. 1 in June 2010.
Djokovic, who'd been No. 1 since winning Wimbledon last year, lost to Federer in this year's semifinals. Nadal, the 2011 runner-up at the All England Club, was upset in the second round in 2012.
Andy Murray, who lost to Federer in Sunday's final, remains at No. 4.
There's also a new leader in the WTA rankings: Victoria Azarenka rises one spot from No. 2, while Maria Sharapova drops from No. 1 to No. 3.
