New York:Roger Federer needed a little over an hour to advance to the second round of the US Open. He beat Ivo Minar 6-1, 6-1, 6-1 in the first match of the defense of his title. Federer said he has purged himself of guilt he used to feel for beating an opponent as easily as he did Minar. "I had the feeling the guy deserves it more than I do. That's a horrible feeling to have inside. No, that feeling is definitely gone. That's good,'' Federer said after needing only 61 minutes to beat the 21-year-old Czech making his US Open debut. Federer has been untouchable the last two seasons, the best run since Pete Sampras reigned. Top Spot He has been No 1 since February 2004, and has won four of the last seven Grand Slam titles, including his third straight Wimbledon crown this year. If he defends his title here, he'd be the first man in the Open era to win both Wimbledon and the US Open in consecutive years. He led 5-0 in the first set before Minar won his first game. He had 12 aces, his fastest serve reaching 208 kph (129 mph). He had 34 winners to Minar's 12, and had only 10 unforced errors. The victory was Federer's 29th straight on hard court, and improved his overall record this year to 65-3. "I really had the sense I was returning very well, hardly giving him any points there, holding easy on my serve,'' he said. "The baseline, I didn't have the feeling I was in any rush at all. That's obviously a good feeling to have from the start of a tournament. That doesn't happen very often going into Slams.''
