Eighth seed Juan Martin Del Potro secured a straight sets win over 4th seed David Ferrer to reach the last four of the men’s singles.
He has reached his first Wimbledon semi final but his condition remains in doubt after he needed to receive treatment after falling heavily on his left knee which was already strapped during the fifth point of the match. The match was delayed for five minutes.
The former US Open winner came back even stronger and cruised to a 6-2 6-4 7-6 (7-5) win in 2 hours and 16 minutes over Spaniard Ferrer who struggled with the skill and determination of the Argentine.
“It’s going to be dangerous if I don’t recover in the next few days,” Del Potro said of his knee.
“I was really close to pulling out, I felt a lot of pain. But the doctor gave me some massive pills.
“I think I played my best tennis in this match, I’m so happy with my level at this moment.”
Del Potro will now face the winner of Novak Djokovic and Thomas Berdych in the semi finals if he is fit enough to play.
