WIMBLEDON, England (AP): Venus Williams is just about the perfect older sibling: She supports Serena endlessly, protects her fiercely, and even lets her little sister pick which bedroom she wants when they're on the road.

Venus draws the line at Grand Slam championships.

The American sisters will come up against each once again in a major final, playing each other on Saturday in the Wimbledon title match for the fourth time.

``I'm happy for her to be in the final, but I have to face her and defeat her,'' Venus said after reaching her eighth final at the All England Club by routing top-ranked Dinara Safina 6-1, 6-0. ``I don't necessarily want her to lose, but for sure I want me to win.''

Venus should have the edge on the new Centre Court, which has a retractable roof over it for the first time in history. Besides having won five Wimbledon titles, Venus also beat Serena in last year's final and is trying to become the first woman to win three straight championships since Steffi Graf from 1991-93.

``Even if she's not playing her best, just that fight she has, you're facing that,'' Venus said. ``So there's so much to face when you play her. It's definitely a lot to get your mind around.''
