Hungarian Agnes Szavay, ranked 31st in the world, defeated seventh-seeded Nadia Petrova of Russia 6-4 6-4 to reach the fourth round of the 2007 US Open.
Petrova had treatment for a left hip injury late in the first set but she was outplayed by Szavay, who is celebrating her biggest success at a Grand Slam so far.
The 18-year-old Hungarian caught the attention of the tennis audience last week when she played in the final of the Pilot Pen Tennis presented by Schick in New Haven. Unfortunately, she had to retire from that match due to a back injury.
At the US Open, Agnes Szavay will next face world No.50 Julia Vakulenko of Ukraine.
