Federer beats Ferrer in semis at ATP Finals

Roger Federer reached his 100th career final Saturday by beating David Ferrer of Spain 7-5, 6-3 in the semifinals of the season-ending ATP World Tour Finals.In a tournament where his biggest rivals complained of fatigue after failing to make it out of the group stage, the 30-year-old Federer showed no signs of slowing down as he extended his unbeaten streak to 16 matches after winning titles in Basel and Paris before coming to London.The former top-ranked Swiss star became just the fifth player to reach 100 finals in the open era, and will be looking for his 70th title overall on Sunday. The victory over Ferrer also means Federer will overtake Andy Murray for the No. 3 spot in the year-end rankings, behind No. 1 Novak Djokovic and Rafael Nadal.He will face the winner of Jo-Wilfried Tsonga and Tomas Berdych, who played in the second semifinal later.Djokovic and Nadal were both eliminated after losing two of their round-robin matches this week, and said their minds and bodies just werent up for top-level tennis following another grueling season. Murray pulled out injured following his opening loss to Ferrer on Monday.But Federer has played some of his best tennis of the year in London, and while he did not look as sharp against Ferrer as he did in his three group-stage victories, he never faced a break point.
