Williams sweeps past Henin easily

Serena won 6-2, 6-0 in the quarterfinals of the Sony Ericsson Open.

KEY BISCAYNE, Fla. (AP) — On a sultry afternoon in the subtropics, Serena Williams sat under an umbrella and sipped a refreshment.

A day at the beach? Almost. When play resumed, Williams made the world’s top-ranked woman look like a beginner, beating nemesis Justine Henin 6-2, 6-0 in the quarterfinals of the Sony Ericsson Open.

Williams won the final 10 games Tuesday by playing nearly flawless tennis, while Henin unraveled after she double-faulted three times to fall behind 4-2.

“It wasn’t easy,” Williams said. “It was just the fact of me making the right shots at the right time.”

Top-ranked Roger Federer advanced to the men’s quarterfinals by beating Jose Acasuso 7-6 (6), 6-2. No. 2-seeded Rafael Nadal swept No. 16 Paul-Henri Mathieu 6-4, 6-4.

Williams’ rout of Henin was a stunner, given the drama usually generated by the rivalry. Williams had lost their past three meetings, all in 2007, at the French Open, Wimbledon and the U.S. Open.

But Williams beat Henin in the Key Biscayne final a year ago, overcoming two championship points.

“I wish this was a Grand Slam,” Williams said with a laugh. “I’m going to try do this at a Grand Slam, and not only at this tournament.”

Williams could meet sister Venus in the semifinals Thursday. The older Williams, a three-time Key Biscayne champion, was to play No. 3-seeded Svetlana Kuznetsova on Tuesday night.

Conditioning can be an issue for Serena Williams, but she has never looked more agile than in the past week. No longer forced to rely on mere power, she lobbed over Henin to stay in rallies, chased down a drop shot to hit a winner and even playing serve and volley.

Seeking her fifth Key Biscayne title, Williams is improving as the tournament progresses. She committed 60 unforced errors in her opening match but had only 15 against Henin.

The Belgian, meanwhile, struggled even with her signature backhand and found herself stuck at the baseline.

James Blake wobbled at the finish but beat Radek Stepanek 6-3, 6-4. The No. 9-seeded Blake needed six match points in the final game to close out the victory.

No. 15 Guillermo Canas, last year’s runner-up, lost to No. 31 Igor Andreev 6-4, 7-6 (6). No. 10 Tomas Berdych beat Dmitry Tursunov 6-2, 6-2.
