Roger Federer ranks No. 1 among all athletes in Australia.

Novak Djokovic tries to keep pace with Roger Federer Sunday at the US Open.

Her fellow players wished Kim Clijsters well as the Belgian player her final singles match today at the US Open.

Sharapova is coming off a few weeks missing play due to a stomach virus, with the pain leading her to take a pregnancy test, which came out negative. Azarenka in a late match rolled over Russian Alexandra Panova 6-1, 6-0.

Some of the weirder injuries suffered by tennis players.

“That’s my game, to serve well and be aggressive,” said Lisicki, who closed out match point on a second-serve ace. “That’s what I did. I think it worked well. As soon as I got the break in the second set, I knew, ‘I’m going to take it home.'”

“I definitely had to dig pretty deep,” Williams said. “She was playing really well, and I had to go out there and do what I could. I hit so many errors off the returns. I was just off. Usually I’m returning really, really well. And I think she played an unbelievable match today. But I think I can play better.”

“I faced her many times in the juniors,” said Sharapova, who was broken twice in the second set. “She used to be a nightmare for me because she used to slice and drop shot on clay. We used to have real battles, and we haven’t played since then. I knew her game really well and she didn’t have time to do all of that today on grass. If I’m hitting a hard-paced shot I don’t think she has time to create, which is something she likes to do. That’s her game, lots of slices and drop shots, get people kind of crazy.”

In other upsets on the women’s side, American Jamie Hampton powered past No. 27 Daniela Hantuchova 6-4, 7-6(1), and France’s Stephanie Foretz Gacon outlasted No. 29 Monica Niculescu 6-4, 3-6, 6-3.

The 126th edition of The Championships at Wimbledon kicks off Monday with a slew of interesting match-ups, including three former No. 1s who are unseeded, Kim Clijsters’ last Wimbledon, and world No. 1s Novak Djokovic and Maria Sharapova in action.

It was Roddick’s fifth title on grass, and through the first six months of the season he is the only American male to win a singles title.

We’re searching for new storylines for the 2012 version of Wimbledon, but it’s looking a lot like the same-old same-old between the “old guard” of the Williams sisters, Sharapova, Clijsters, etc. Isn’t this around the time of year that Justine Henin makes a comeback? Martina Hingis in doubles? Yawn…we need some shake-ups in women’s tennis. Was 2011 just a fluke for Petra Kvitova, who could not claim a grasscourt title coming into the All England Club this year?

“When I started the tiebreak, I said, ‘Francesca, come on, pay attention and take two or three of the first six or seven points.’ Nothing, 6-0,” Schiavone said. “I went to the other side and told myself there is not too big a difference in winning or lose one point, so keep going and push. We will see what happens. And then I won.”

Andy Roddick’s downward trajectory, the return of Kim Clijsters, and reigning Wimbledon champ Petra Kvitova in action are the things to watch this week, the final warm-up week before Wimbledon.

Kim Clijsters will not play the French Open.
