Federer could be on track to smash Sampras’ record

SWISS master Roger Federer may seem a superhuman sports star to his fans around the world.

But, after trouncing Australia's Lleyton Hewitt in three straight sets on Sunday in one the most dominating performances in US Open finals history, he looked and felt particularly uninspired.

"I'm exhausted," said the 23-year-old, immediately after the winning his first four grand slam finals.

"There is a chance I might even get sick because I already felt it the last two days.

"The next two weeks are important to recover and get ready for the rest of the season so I don't get injured."

Federer continues to set records with every fresh victory. He has won four grand slams, 20 career singles titles and more than $US15million in prize money.

"Every grand slam had something different," he said. "Wimbledon was my first grand slam win.

"Australian Open was my first tournament without a coach, just to see how things would be. And then defending the Wimbledon title was something I had never done.

"Now winning my first US Open it puts an end to a great season."

He is the first player to win Wimbledon and the US Open in the same year since Pete Sampras in 1995.

And with the victory, the Swiss world number one improves his grand slam record since the 2003 French Open to 32-2.

It has also prompted many, including Hewitt, to suggest he could be on his way to surpassing the Pete Sampras record of 14 majors.

But the modest Swiss refused to believe he was ready to make a run at Sampras' record, saying that finishing number one at the end of the year for the first time was his immediate priority.
