Let others wonder whether Denmark's Caroline Wozniacki merits the No. 1 seeding at the U.S. Open, the first time she's been awarded the top spot at a Grand Slam tournament. She harbors no doubts. "Pressure is when you're put on the spot and you don't feel like you belong there, don't think you deserve to be there," Wozniacki said Sunday, a day before play begins at Flushing Meadows. "I think I deserve to be where I am, and I think that I'm feeling comfortable there." She is currently No. 2 in the WTA rankings, behind Serena Williams, who pulled out of the U.S. Open more than a week ago, citing surgery to repair cuts on her right foot. The U.S. Tennis Association strictly follows the rankings when assigning seedings, so Wozniacki got the top spot. That made her the first woman since Kim Clijsters in 2003 to be seeded No. 1 at the U.S. Open without already having won a major championship. The 20-year-old Wozniacki also is the youngest woman to lead the field since Maria Sharapova was 18 in 2005. http://sports.espn.go.com/sports/tennis/usopen10/news/story?id=5509646
