Spanish world No. 1 Rafael Nadal rolled over Switzerland's Roger Federer 7-5, 6-3 Sunday in the semifinals of the Barclays ATP World Tour Finals.

"The second break in the second set was very important. Winning the first set was important, but it's always complicated with Federer because he plays all out and makes you feel the match is in his hands," the 27-year-old Nadal told Teledeporte.

The win allowed Nadal, who has won 13 Grand Slam titles, to qualify for the final of the season-ending tournament for the second time in his career.

"I went for it when I had a chance for a break point in the first set," Federer said. "Maybe I shouldn't have, but I did. I just struggled to stay consistent enough throughout the match and that's why he deserved to win. He was better today."

Nadal will take on the winner of the semifinals match between Serbia's Novak Djokovic and Switzerland's Stanislas Wawrinka in the championship match.

"Historically, this is the one where I have done the worst, but tomorrow I am going to do everything possible to win it. Whatever happens, come what may, this has been one of the best years of my career," Nadal said.

The 32-year-old Federer is the oldest player to finish the season in the top 10 since Andre Agassi did so at age 35 in 2005.

"He was playing more solid. I just couldn't come up with the shots when I needed them, forehand or serve, moving forward," Federer said.

The Barclays ATP World Tour Finals, which is being played at London's O2 Arena, is the biggest tournament on the men's tennis calendar after the four Grand Slams. EFE
