Switzerland's Patty Schnyder, who reached the quarter finals at Flushing Meadows two years ago, has been pushed out in the second round of the US Open by a little-known Japanese player.

She suffered a straight sets defeat on Thursday at the hands of Shinobue Asagoe.

Schnyder, who is ranked 22nd in the world, failed to capitalize on her superiority as a player over 94th-ranked Asagoe, and lost the match with a final score of 7-5 6-4.

The defeat dampens enthusiasm among Swiss tennis fans who'd hoped to see Schnyder join Martina Hingis in the third round. But, on the doubles side of the New York tournament, there was more encouraging news.

Schnyder and her partner, Nadejda Petrova of Russia, made it through to the second round with a 6-1 3-6 6-3 win over Silvia Farina and Karina Habsudova.

On the men's front, there were doubles victories for both Roger Federer and Marc Rosset. Federer, and his team-mate Andrew Kratzmann of Australia, beat Aleksander Kitinov and Jan Siemerink 6-4 6-4. Rosset, for his part, enjoyed a 2-6 6-4 7-6 (7/5) victory with his Italian partner, Andrea Gaudenzi, over Marcos Ondruska and Antonio Prieto.
