Rafael Nadal said on Thursday his decision to withdraw from Wimbledon, due to an abdominal injury, was “out of respect to myself”. “I made my decision because I believe that I can't win two matches under these circumstances. I can't serve,” the 22-time Grand Slam champion said while announcing his pullout a day ahead of his much-anticipated semifinal clash with Australian Nick Kyrgios. “It's not only that I can't serve at the right speed, it's that I can't do the normal movement to serve.” “I have to say that, for respect to myself in some way, I don't want to go out there, not be competitive enough to play at the level that I need to play to achieve my goal, and with a big chance to make the things much worse, no? “As I always said, for me the most important thing is happiness more than any title, even if everybody knows how much effort I put to be here. But I can't risk that match and stay two, three months outside of the competition because that's going to be a tough thing for me.”
