LUXEMBOURG (AP) — Top-seeded Caroline Wozniacki of Denmark will play Annika Beck of Germany in Sunday's final of the Luxembourg Open.

Wozniacki, ranked ninth in the world, swept past third-seeded Sabine Lisicki of Germany 6-4, 6-4. She has lost only one set all week.

Beck advanced to her first WTA final when Stefanie Voegele of Switzerland had to retire hurt at 7-5, 1-0 in their semifinal.

Wozniacki has 20 career titles, but yet to win one this year. She and Beck will meet for the first time.
