Wimbledon, England ? Five years since their last title matchup, the Williams sisters are back in the Wimbledon final with another Grand Slam championship at stake.

The sisters won in straight sets Thursday to set up their seventh all-sibling final at a major and third at Wimbledon.

Defending champ and four-time winner Venus beat Elena Dementieva 6-1, 7-6 (3), then two-time champ Serena served 14 aces to top China’s Zheng Jie 6-2, 7-6 (5).

It will be the first all-Williams final since 2003, when Serena beat her older sister in the Wimbledon final for the second year in a row. Serena will be going for her ninth Grand Slam title; Venus her seventh.

“It’s definitely been a while,” Serena said. “We’ve been on the same side of the draw a few times. It’s good. This is a new start for us.”

Said Venus: “It’s every Williams for themself.”

Serena holds an 8-7 career edge over Venus, including 5-1 in Grand Slam finals. Since Venus won the U.S. Open in 2001, Serena has won all their major finals.

“It’s easy, especially with sibling rivalry,” said Serena, who has also reached the women’s doubles semifinals with her sister. “I personally want everything that Venus has. We’re good at this now.”

Venus improved her record to 7-0 in semifinals at Wimbledon.

In men’s play, Rainer Schuettler outlasted Arnaud Clement 6-3, 5-7, 7-6 (6), 6-7 (7), 8-6 in a match that lasted more than five hours over two days. The German saved a match point at 5-4 in the fifth set before pulling out a victory that sends him into the semis today against No. 2 Rafael Nadal. The other men’s semifinal has Roger Federer facing Marat Safin .
