Defending champion Roger Federer qualified for the semi-finals at the Barclays ATP World Tour Finals with a 6-3, 6-0 demolition of his fierce rival second seed Rafael Nadal.
Federer won his first match over Nadal since last year's final at the year-end championship, by hitting 28 winners to four in a 62-minute win Tuesday. It was their fifth meeting in England.
"It was a great match for me basically from start to finish," said Federer. "I was able to do what I was hoping to do -- dominate from the baseline, play close to the baseline, serve well, take his time away. (It) hasn't always worked."
"I always knew I could beat Rafa. The question is sometimes it was hard to do because he has a big say, as well, in how the matches go. The quicker the court, the more I favour myself. Maybe Rafa didn't play his very best tonight. But on an indoor court, it all happens very quickly as we saw at the end. For me it was an exciting match to play," said the Swiss who has won five titles here.
Federer broke Nadal's serve to love for a 4-2 lead and went onto close out the first set in 32 minutes, having hit 12 winners - including nine off the forehand wing - and winning 17 of 21 first service points.
