After seven years of trying, fifth-seeded Stosur finally overcame her second-round jinx at Flushing Meadows with a storming 6-1, 6-4 victory over fellow Australian Anastasia Rodionova.

''I just wanted to go out there and stamp my authority on the match from the start,'' Stosur said.

''I was playing well and the body language and everything else just flowed on from there. I wasn't going to allow myself to get into a hole or have anything changed.''

Stosur's reward for burying her demons and being Australia's lone survivor in the women's singles following Sally Peers's second-round loss yesterday to titleholder and two-time champion Kim Clijsters is a seed-free passage to the second week.

The French Open runner-up will play Sara Errani tomorrow for a berth in the last 16 after the unseeded Italian scored a surprise 6-2, 6-3 win over Russian Alisa Kleybanova.

Stosur, though, insisted she hadn't earned the right to look too far ahead in New York, especially after staving off four match points to see off Errani in a third-set tiebreaker last week in Cincinnati.

''It's funny how so quickly you can turn around and play the same player again,'' the world No6 said.

''Looking back in hindsight, maybe that was a really important match to get through. I think it was anyway.

''Maybe that will play on her mind a little bit going into our match.''

Success over the Italian would likely thrust Stosur into a fourth-round confrontation with two-time Grand Slam finalist and 12th seed Elena Dementieva.

Clijsters ended Peers's dream Grand Slam debut with a 6-2, 6-1 triumph over the Melbourne teenager.

Despite the defeat, Peers said she had the time of her life in the feature night match at Arthur Ashe Stadium.

''I didn't want it to end. I was having a really, really good time,'' the 19-year-old said. ''It was a dream come true. If there was one of the top players to choose to play, it would have been Kim for sure.''

Peter Luczak also bowed out but was hoping his gallant 6-7 (8-10), 7-5, 6-4, 6-2 first-round loss to world No36 Sergiy Stakhovsky was enough to convince Davis Cup captain John Fitzgerald he could do the job for Australia in this month's World Group play-off against Belgium in Cairns.
