The pair showed no mercy against their lower-ranked rivals and each romped to victory in 73 minutes after near gale force winds produced some farcical moments at the last grand slam of the season. Sharapova was aced by American Beatrice Capra when she took an undignified swing at a ball that was swept out of her reach by a gust of wind while Wozniacki was gifted a winner after a seemingly harmless forehand bounced and was blown over the head of the perfectly-positioned Chan Yung-Jan and into the stands.Serving was a lottery with players often forced to re-toss the ball while umbrellas, towels and litter blew onto the court and forced several points to be replayed. For most of the top players, the blustery conditions made no difference to their results. Roger Federer won in straight sets again, as did his likely quarter-final opponent, Sweden's Robin Soderling.
The lone major casualty was Serbia's Jelena Jankovic, the fourth seed, beaten 6-2, 7-6 by Kaia Kanepi of Estonia. On one of her serves, Jankovic only managed to catch the ball with the frame of her racket. “I had a really hard time hitting the balls,” said Jankovic, the highest-seeded player beaten at Flushing Meadows this year. “You hit the ball one direction, it goes another. You're just getting ready to hit the ball and it just moves away from you.” Even Federer struggled to cope with the conditions.
Although he comfortably won his center court match with Frenchman Paul-Henri Mathieu 6-4, 6-3, 6-3, he was also reduced to playing it safe and hitting down the middle. “I thought I played great today in the wind,” he said. “It was so hard and I'm kind of relieved to get through.” Sharapova was at her most ruthless in her 6-0 6-0 whitewash over teenage wildcard Beatrice Capra. The Russian was upset by local teenager Melanie Oudin in New York last year but made sure there was no repeat this time as she moved into the last 16 for the first time since she won the championship four years ago. “This was a new day. What happened last year, I didn’t really want to go into the match thinking about it,” Sharapova said. “On a day like today, I just wanted to make sure I was consistent and did the right thing, maybe didn’t go for the lines as much and just played smart tennis.”
