Caroline Wozniacki of Denmark was seeded No. 1 at a Grand Slam tournament for the first time Tuesday, getting the top spot at the U.S. Open because Serena Williams pulled out with a foot injury. Wozniacki, ranked No. 2 behind Williams by the WTA, was the runner-up at Flushing Meadows last year and is the first woman since 2003 to be seeded No. 1 at the U.S. Open without already having won a major championship. Defending champion Kim Clijsters was seeded No. 2 by the U.S. Tennis Association, which stuck strictly to the rankings in determining the seedings. Venus Williams, the 2000-01 U.S. Open champion, is No. 3, followed by 2008 runner-up Jelena Jankovic and French Open runner-up Samantha Stosur. Two other past U.S. Open champions who were seeded are No. 11 Svetlana Kuznetsova and No. 14 Maria Sharapova. Read more: http://sports.espn.go.com/sports/tennis/usopen10/news/story?id=5493049
