Roger Federer vows to bounce back
Roger Federer made his earliest exit from Wimbledon for eight years but vowed to come back stronger and hungrier than ever. The six-time champion crashed out 6-4 3-6 6-1 6-4 in Wednesday's quarter-finals to world number 13 Tomas Berdych, who will play third seed Novak Djokovic in his first Wimbledon semi-final. It was only Federer's second defeat at Wimbledon since he went out at the first-round stage to Mario Ancic in 2002. And after also failing to reach the semi-finals at the French Open, Federer has suddenly lost his air of invincibility. "I can't wait for Paris and Wimbledon to come around next year, that's for sure, because they've been frustrating tournaments for me," said Federer. However, the Swiss ace has warned his rivals not to write him off, insisting he can regain his position of world domination. "Yeah, I do think that," he insisted. "That's why I'm here." Federer also took some of the gloss of Berdych's fines
