Danish teen Caroline Wozniacki, never before in the last eight at a Grand Slam, advanced to the US Open final by defeating Belgium's 50th-ranked Yanina Wickmayer 6-3, 6-3, on Saturday. Wozniacki, the ninth seed, won a matchup of 19-year-olds to put herself into Sunday's championship match against Belgium's Kim Clijsters, who dethroned defending champion Serena Williams of the United States 6-4, 7-5. 'It feels fantastic,' Wozniacki said. 'I'm really excited.' Wozniacki, who has never played Clijsters, won her 11th match in a row, including a title run at New Haven the week before the US Open began, and is set to reach a career-best seventh in the next world rankings. Nearly eight hours of drizzle delayed the start of the match and forced it to be moved from Arthur Ashe Stadium to the secondary Louis Armstrong Stadium once the showers stopped and the courts could be dried. 'Maybe actually it was easier because you didn't really feel that you were in the semi-finals,' Wozniacki said. 'You didn't feel the pressure too much that actually you're so close to being in a final.' After losing the opening point on her serve, Wickmayer complained to umpire Lynn Welch about the slick surface, sliding her foot along the court to a near-splits position to show her concerns. 'I didn't want to risk getting an injury because the court was a little bit slippery, so we agreed to wait a little bit until it dried out,' Wozniacki said. Welch sent both players to their chairs, scuffed the lines with her feet and the lines were toweled off before the match resumed. Wozniacki and Wickmayer exchanged service breaks to open the match but the Dane broke again in the fifth and seventh games for a 5-2 edge. Wickmayer broke back at love to 5-3 but surrendered four of the next five points, netting a backhand volley to give up the break and drop the first. After a second-set exchange of breaks in the fifth and sixth games, Wozniacki took the critical break in the eighth when Wickmayer netted a backhand, then held serve to win the match after 96 minutes. 'We had been waiting all day so it was just about getting the feet going and to get as many balls back as possible,' Wozniacki said. 'Today was really difficult circumstances.' Wickmayer, whose mother died of cancer at age nine and whose father gave up his construction job so his daughter could follow her tennis dream, had longed for a finals matchup against her idol Clijsters. Instead, Wozniacki became the first Danish man or woman to reach a Grand Slam final, surpassing the 1978 Australian Open women's quarter-finals run by Dorte Ekner as her homeland's best showing.
