Williams didn't want to look ahead just yet Friday.
"I have a very tough fourth-round match," Williams said after beating Milagros Sequera of Venezuela 6-1, 6-0 in the third round. "I have to get over that hump first."
Williams lost to the top-ranked Henin in the quarterfinals of the French Open this month, and the Belgian went on to win her third consecutive title at Roland Garros. At Wimbledon, Williams is just getting started.
"I'm ready to play now," she said after beating Sequera in 43 minutes. "This is great. I couldn't be more ready to compete in any event."
Williams struggled in the first round and complained of a tight hamstring. After winning her second-round match, she said it was no longer bothering her.
"My hamstring is a lot better, which I'm really excited about," said Williams, the surprise Australian Open champion who compiled a 27-3 edge in winners Friday. "It's the first time it's felt this good."
That could be dangerous for Daniela Hantuchova, Williams' next opponent. The 10th-seeded Slovak beat No. 19 Katarina Srebotnik of Slovenia 2-6, 6-3, 6-4.
THE REAL NO. 1: Even Roger Federer still gets excited for matches, especially against former Grand Slam champions such as Marat Safin.
"It's such a big occasion for both of us, because for me it's to prove I'm the real No. 1 and for him it's proving he can still be No. 1," Federer said after beating the Russian 6-1, 6-4, 7-6 (2). "So it's a big match and a very prestigious match."
POKER FACE: Not everything is going great for Andy Roddick at Wimbledon.
The third-seeded American reached the fourth round at the All England Club on Friday by beating Fernando Verdasco 6-3, 6-4, 7-6 (2), but off the court, he and coach Jimmy Connors have been having a separate competition.
"I don't want to talk about us playing cards because it hasn't been good for me this week," Roddick said. "I have to win my next round just to ... Never mind."
