London, Jul 3 (EFE).- Serbian world No. 1 Novak Djokovic beat the Czech Republic's Tomas Berdych 7-6 (7-5), 6-4, 6-3 in their quarterfinal showdown Wednesday at Wimbledon.
The 26-year-old Djokovic's opponent in the semifinals will be Argentina's Juan Martin del Potro, the No. 8 seed, who defeated Spain's David Ferrer, the No. 4 seed, 6-2, 6-4, 7-6 (7-5).
Del Potro overcame a fall early in the match that injured his left knee and gave him a fright.
"I thought about too many negative things because the same thing happened to me four days ago, and I knew that (the doctors) could not do anything more. At first, I was a little scared when the doctors said they couldn't do anything more, just give me anti-inflammatories," the 24-year-old Del Potro said.
Andy Murray, who is trying to become the first British man to win Wimbledon since 1936, had a scare of a different kind against Spain's Fernando Verdasco, the world No. 54, dropping the first two sets in the match.
Murray, the world No. 2, needed three hours and 27 minutes to come back and beat the 29-year-old Verdasco 4-6, 3-6, 6-1, 6-4, 7-5.
The 26-year-old Murray's next opponent will be Poland's Jerzy Janowicz, the world No. 22, in his fifth semifinal at the All England Club.
Janowicz beat countryman Lukasz Kubot, who is ranked 130th in the world, 7-5, 6-4, 6-3 to advance to his first Grand Slam semifinal.
Janowicz won the first-ever meeting between Polish players at a Grand Slam event.
The Pole, who is 22 years and 236 days old, is the youngest player to advance to the semifinals in London since Murray made the semis at the age of 22 years and 51 days in 2009.
