Federer is in a very tight fourth-round match at one set all. I feel like he would have rolled over this opponent a year ago.

Quoted: "I think Federer has been relying too much on his talent than hitting the gym in the last 18 months. Him not getting any stronger has taken its toll on his results recently."

I love Federer, but I am happy to see Blake, the American, inch closer to a tennis medal. Now, I hope that Paes-Bhupathi defeat Federer in doubles!

Quoted: Roger Federer's dream of an Olympic medal in singles will have to wait until 2012 -- he does still does have doubles this year -- because James Blake has knocked him out and advanced to the semifinals.

Nadal could become #1 very soon.

Quoted: World number two Rafael Nadal could now usurp the Swiss at the top of the rankings should he win in Cincinnati.

Looks like Nadal will take over the #1 ranking from Federer on August 18th, and potentially sooner.

Quoted:The 22-year-old has a chance of ending the Swiss star's reign at the Cincinnati Masters this week.
...
For that to happen, Nadal will must win the title and hope Federer loses before the semi-finals.
...
If not, Federer's four-and-a-half year stint at the top of the rankings seems likely to end on 18 August when he loses the 850 points he gained for reaching last year's Toronto final and winning in Cincinnati.

Apparently John McEnroe cried while interviewing Federer.

Quoted: John McEnroe cried interviewing Roger Federer and I could swear he is crying now interviewing Rafa Nadal

John McEnroe busts out the "thank you man" hug for Roger - I'm having problems believing I actually witnessed that just now...

Hmm, looks like Federer is in a little rut.

Quoted: Roger Federer lost again, this time in one of the biggest tennis upsets in memory. Mardy Fish, an American ranked 98th, shocked No. 1 Federer in straight sets Saturday, with the lopsided score -- 6-3, 6-2 -- making it even more of a stunner. Fish, who pulled off by far the biggest of his upsets he's strung together this week in the Pacific Life Open, moved into Sunday's final against No. - Tennis news

Good point..nothing settled.

Quoted: But as far as settling who might be the better of the two, forget about it. Sampras, lacking match play, is now 36 years old and in his sixth year of retirement. Federer, a decade younger, is in the midst of perhaps the worst start of his career.

The 26-year old Federer edged the 36-year old Sampras in this exhibition match.

Quoted: "I don't think winning or losing was really the issue tonight," said Federer, who perhaps found it easier to think that way as Monday turned into Tuesday, given that he did come out on top 6-3, 6-7 (4), 7-6 (6). "The winner was tennis. The winner was tennis in America."
