Rafael Nadal struggled on a sore left knee past unheralded Australian Alun Jones on Wednesday to reach the second round of the US Open, but his bid for a third Grand Slam final in a row appears doomed. Severe tendinitis slowed the second-ranked Spaniard, who escaped with a 7-5, 3-6, 6-4, 6-1 victory after two hours and 44 minutes over a 123rd-ranked wild card.
World number ones Roger Federer and Justine Henin breezed over qualifiers on Monday into the second round of the United States Open, while reigning grand-slam champions Serena and Venus Williams also advanced handily. Three-time defending champion Federer defeated American Scoville Jenkins in 92 minutes.
