VILLANOVA, Pa. (AP) -- Lindsay Davenport easily dispatched of Venus Williams in the semifinals of the Advanta Championships with a booming serve that threw her opponent off balance the whole match.

It may not be that easy against Martina Hingis, the top-ranked player in the world, when the two meet in the finals Sunday.

Second-seeded Davenport fired nine aces against Williams in a 6-1, 6-2 win Saturday to send her to Sunday's finals against the top seed Hingis, who beat Nathalie Tauziat 6-4, 6-2 in the other semifinal.

Davenport's dominating performance isn't enough to dim Hingis' hopes of winning her second Advanta title in three years.

``It's going to be quite exciting playing her again. She didn't have a letdown the whole match,'' Hingis said. ``She was pretty impressive.''

Davenport complemented her service game by breaking third-seeded Williams' serve four times.

``Wow, it's one of the best matches I've served, probably ever,'' Davenport said. ``I don't think I was ever in trouble with my serve. Maybe the first time I served I got to 30-30, but when you're able to serve so well, you put more pressure on the other person's serve.''

Williams' strong service game was neutralized by eight double-faults, including four in the decisive game that was most indicative of the 50-minute match.

After landing a forehand winner down the line to thwart Davenport's first match point, Williams never connected on her next two serves. She double faulted on the last serve as the ball sailed into the net and Davenport raised her fists in victory.

``She served nicely, it's always a plus. It just makes the game a lot more easier,'' said Williams, ranked third in the world.

It was the fifth meeting of the year between the two young Americans, with Davenport ending a two-match losing streak.

Williams gained some momentum after tying the second set 1-1 on an ace and three unforced errors by Davenport.

But the 23-year-old Davenport went on to win 12 of the next 15 points, including a forehand smash past a frozen Williams at the net that gave her a 4-1 lead.

Williams, a baseliner trying to improve her serve-and-volley game, failed miserably. Most of her volley attempts hit the net or landed wide of the sidelines.

``She felt a lot of pressure on her serve and gave me a lot of free points on double-faults,'' Davenport said. ``Some of the second serves that were going in were semi-attackable. But I was able to break easily a lot of times and hold my serve at the same time.''

The win moves Davenport on to her third straight Advanta finals, having lost he last two years.

Tauziat kept up with Hingis early in the first set, with the two exchanging service breaks and playing to a 4-4 tie.

Hingis went on to win the next two games convincingly, dropping a forehand past an advancing Tauziat, then serving an ace to win the set 6-4.

Hingis' serve-and-volley game proved too much for Tauziat in the 6-2 second set.

Davenport pulled out of her semifinals doubles match with Connie Marariu Saturday night in order to rest an aching left wrist for Sunday's singles final. It allowed Chanda Rubin and Sandrine Testud to move on Sunday's doubles final against Lisa Raymond and Rennae Stubbs.
