Roger Federer faces Big Test at 2007 U.S. Open Saturday

Literally.

And although I don't mean Roger Federer will be having a hard time dismantling this guy, I do mean he'll be facing a BIG TEST on Saturday LITERALLY when the No.1 player in the world plays the third round of the 2007 United States Open Championships.

Hell, the guy he's facing this Saturday stands at 6'9'' and definitely STANDS OUT from the crowd. Although nobody really knows him that much, John Isner (yep, we're talking about him...) should now be known as the giant freak who tried to bring down Roger Federer when he loses to Federer this weekend.

The big man on campus, the biggest story in the 2007 U.S. Open Championships, (and basically any other cliché with the term ''giant'' or ''big'' in it...) defeated Rik De Voest in the second round of the last grand slam of the tennis calendar year, setting up a third round face-off with the current king of the tennis court.

John Isner is only 22 years old. Yes, he can very well pass as a fraternity boy or something. Hell, this dude can even pass as Britney Spears' newest boy toy for heaven's sake.

Hell, he got some game too. The boy has this first serve that can literally make your neck snap. His coach, Manuel Diaz, is rooting for his boy to win it all at the 2007 U.S. Open Championships.

''Right now he's on cloud nine. The way he's hitting his ground strokes, he's on a totally different level than he was a month ago. That's all confidence,'' Diaz said.

If there's one thing Diaz can describe John Isner, it's probably the fact that he's always eager to learn.

''One of the first things I told him was, 'You need to be a serve and volleyer,' I expected him to question it or get frustrated. But that was one thing off the bat that set him apart. He bought into it right off the bat.''

Of course, he'll still get creamed by Roger Federer come Saturday of course.
