Roger Federer ousts David Ferrer to reach ATP World Tour Finals last four at 02 That did not tell the whole story, though, as he fought off six break points, and they were back level after Ferrer finally took his eighth chance. He was pushing Federer, who was making quite a few errors but, as he so often does, the world number two found another gear when he needed it to break to love and secure the opening set. Ferrer had another opening at the start of the second set but could not take it, Federer saving two more break points. The set was very tight and Ferrer stayed with his opponent all the way until the tie-break, but an error on the sixth point proved crucial. Federer had been immaculate on serve and took his third match point when a Ferrer return dropped long to become the first singles player through to the semis.
