The 25-year-old has not won a title in four straight tournaments - his worst run since becoming world number one in February 2004. Against Volandri, he hit only two winners with his forehand, normally his best shot, and made 44 unforced errors to Volandri's 23. "I don't know what's wrong. I have to analyze it myself," said Federer. "It was over too soon for me today. "I need to get back on the practice courts instead of the match courts. "On clay you need to be solid, and I wasn't. I don't know if you can say I was playing shockingly, but I was making a lot of mistakes, serving badly - giving him second serves all the time. "It sometimes happens, but usually I get through. And Volandri played well." -Full Story (BBC Sport)
