Serbia's Novak Djokovic advanced to the Wimbledon round of 16 with a routine 6-4, 6-2, 6-4 victory Friday over Frenchman Gilles Simon.
The world No. 2 and 2011 champion delivered an impressive performance on Centre Court, dictating the points from the baseline and effectively using the drop shot against an opponent who is skilled but lacks a potent weapon.
Simon, whose ranking has fallen from 19 at the end of last year to 44 at present, hurt his cause by making a lot of errors in the net.
Djokovic was unhappy with himself after gifting some points at the start of the second set, but he quickly righted the ship to take a two-set-to-love lead after an hour and 20 minutes of play.
The Serbian had a scare in the third set when he slipped and fell and seemed to hurt his shoulder, but he later continued without any apparent problems after receiving medical attention.
Djokovic will next take on Frenchman Jo-Wilfried Tsonga, a 6-2, 6-2, 7-5 winner Friday over Taiwan's Jimmy Wang, for a spot in the quarterfinals.
The Serbian six-time major champion has a streak of 20 consecutive Grand Slam quarterfinal berths dating back to the 2009 Wimbledon.
He lost in the 2013 Wimbledon final to Scotland's Andy Murray, who became the first British player in 77 years to win tennis' most prestigious tournament.
Simon, meanwhile, was unable to equal his best-ever result at Wimbledon - a fourth-round berth in 2009, when his run was ended by Spain's Juan Carlos Ferrero.
In a major upset in the women's singles on Friday, China's Li Na, the No. 2 seed, lost to Czech Barbora Zahlavova Strycova 7-6 (7-5), 7-6 (7-5). EFE
