World number one Kim Clijsters, still searching for her first Grand Slam title, has coasted to a 6-2 6-4 victory over American number 17 seed Meghann Shaughnessy at the US Open.
Belgian Clijsters was helped by 34 unforced errors by Shaughnessy that accounted for over 50 per cent of the points she won. She also never faced a break point.
“She made a lot of mistakes, definitely with her forehand return,” Clijsters said. “I created a lot of opportunities for myself to win, to have short points and to keep them short.”
Fifth seed Amelie Mauresmo of France secured a quarter-final berth by dumping unseeded Tamarine Tanasugarn of Thailand 6-2 6-3. Mauresmo will play Clijsters in the quarter-finals.
Wimbledon champion and number two seed Roger Federer completed night play with a 6-3 7-6 (7/4) 6-3 victory over American James Blake.
Federer capitalised on his only break-point chance in the first set for a 6-3 triumph and the duo became engrossed in a riveting second set.
Blake staved off an amazing 19-of-20 break-point opportunities, surviving 10 deuces in one service game, and got into a tiebreaker. Ultimately, the Swiss number one took the set and finished the match in set three.
“I don’t know how many (break points) I missed, especially in the second set - (commentator John) McEnroe told me (in a post-match interview),” Federer said. “That just happens, I should have made maybe the first or the second. I always felt in control of the second set. They were cheering like he won the match when he just held serve.”
Number 13 David Nalbandian of Argentina needed four sets to get by 20th-seeded Australian Mark Philippoussis 7-5 6-7 (10/12) 6-3 6-2, in a match up of the last two Wimbledon runner-ups.
Nalbandian advanced to meet Federer, an opponent he has beaten in all four career meetings.
Xavier Malisse of Belgium defeated Russian qualifier Dmitry Tursunov 7-5 6-4 7-6 (10/8). Malisse next encounters Roddick, who has beaten him all seven times.
