After last night's exhilarating action, we've got some great tennis to follow up.

At 11am, Justine Henin plays at Ashe while Novak Djokovic plays at Louis Armstrong. In the afternoon, Ana Ivanovic, Tim Henman, Marion Bartoli and Serena Williams all play.

Lleyton Hewitt will play on Louis Armstrong at night, while Venus Williams and the injured Rafael Nadal play at Ashe.

Match to watch for: Mardy Fish v. Tommy Robredo at 1pm on Ashe. Fish is hot and he gets the big stage to take on the nunmber 8 player in the world. A solid chance for a major upset.

No surprises so far today. Martina Hingis and Lleyton Hewitt both won easily and Novak Djokovic is cruising.

A young American contender, Sam Querrey, lost easily in straight sets, so he won't join unheralded countrymen Donald Young and John Isner in the second round.

Pay attention to James Blake's match, which is playing out very, very tight early on.

Is former champion Lleyton Hewitt the dark horse of this year's open?

That's the talk around here this week and if today's match was any indication -- he rolled over University of Illinois grad Amer Delic in straight sets -- he's in his best form in years.

"When you feel confident within yourself, you're happy with where your game's at, you enjoy it a lot more," he said today.

Hewitt, a 26-year-old 16th seed, won his two Grand Slams when men's tennis was in a tattered state -- post-Sampras, pre-Federer.

Since the advent of Federer and Nadal, Hewitt was left in the dust.

"Roger or Nadal, they're consistent and they have the firepower," Delic said today. " I think that's where Lleyton gets lost a little bit."

But Hewitt has made the argument this year that his game -- he's arguably still the best serve-returner in tennis -- is coming back to form.

In his last Grand Slam at Wimbledon, he made it to the 4th round and lost a knock-down, dragout five-setter to Novak Djokovic. And in a tournament in Cincinnati a couple of weeks ago, he brought Roger Federer the distance in a semifinal in which Federer needed two tiebreaks to win.

Hewitt, who last won at Wimbledon in 2002, thinks he's still got what it takes to win another Grand Slam.

"I believe that, yeah, it's in me, that's for sure."
