Federer opens Basel campaign in style, Nadal also progresses

BASEL (Reuters) - Roger Federer began his pursuit for a sixth Swiss Indoors Basel title with an explosive 47-minute 6-2 6-1 victory over Gilles Muller on Wednesday after Rafael Nadal reached the quarter-final with a 6-1 6-1 win against Pierre-Hugues Herbert.

Top seed Federer hit 12 winners in a 24-minute first set and the Swiss 17-time grand slam champion continued his domination in the second set without losing a single point on his serve.

Such has been his form since falling as low as world number eight in March that the 33-year-old could end the season top of the rankings.

"It was a very easy match. He couldn't do anything on my serve. He was struggling with the return," Federer told reporters.

"I'm happy I had a quick match, because I have a lot of matches in the coming weeks. Gilles' game completely fell apart and his level dropped. It was a great first round for me."

Nadal, playing through appendicitis, was equally impressive, needing just 57 minutes to dispatch France's Herbert.

The former world number one, who could miss the season-ending ATP World Tour Finals next month depending on surgery, broke his opponent's serve five times in a second seamless victory in three days.

"I'm still very tired during the matches," Nadal told a press conference. "But physically I'm improving. I feel much better than a few days ago. I'm surprised that I advanced that easy to the quarter-finals. I didn't expect that before the tournament."
