NEW YORK, NY, USA - The first round continues at Flushing Meadows on Tuesday, with Samantha Stosur, Simona Halep and Svetlana Kuznetsova all in action.

Tuesday, First Round

Louis Armstrong Stadium
[11] Samantha Stosur (AUS #11) vs. [Q] Victoria Duval (USA #296)
first meeting
Tuesday's final match on Armstrong is a classic battle of youth versus experience as Victoria Duval takes on 2012 champion Samantha Stosur. At 17, American qualifier Duval is the third youngest player in the draw and with only 60 senior matches under her belt - five of which have come in WTA main draws - she is also the greenest.

Despite recently splitting with long-term coach David Taylor, Stosur enters the year's final major with a spring in her step following an encouraging summer on the hard, highlighted by a fourth career title - and a first victory over World No.2 Victoria Azarenka - in Carlsbad. Duval has never before faced a Top 20 opponent and Stosur and her topspin loaded groundstrokes will provide a tough introduction to life at tennis' top table.

Court 17
[27] Svetlana Kuznetsova (RUS # 29) vs. Mallory Burdette (USA #96)
first meeting
Twelve months ago, a third round run in New York convinced Mallory Burdette to temporarily put her studies at Stanford on hold in favor of a crack at professional tennis. So far the gamble appears to be paying off, as Burdette has rapidly climbed the ranks and established herself as the latest bright young American talent in the Top 100.

Her opening round opponent, Svetlana Kuznetsova, has been hampered by an abdominal injury of late, contributing to early exits at Carlsbad, Toronto and Cincinnati. However, the Russian, who won the title here in 2004, knows how to raise her level when it matters and her smooth, all-court game is sure to test how far Burdette has progressed in her first year on tour.

Court 11
[21] Simona Halep (ROU #19) vs. Heather Watson (GBR #76)
first meeting
Simona Halep has certainly had a summer to remember. After a slightly underwhelming start to the year, the Romanian has compiled a 25-3 record since June, picking up four titles on three surfaces and breaking into the Top 20 for the first time.

Placed in a relatively open section of the draw, Halep will be quietly confident of continuing this good form at Flushing Meadows, where she has never previously been beyond the second round. First up, she faces Heather Watson, who is still searching for form and fitness after a debilitating bout of glandular fever in the spring. Watson has good memories of the tournament, having won the junior title in 2009, but faces an uphill struggle if she is to halt Halep and register her first career Top 20 win in the process.

Around the grounds?
No.2 seed Victoria Azarenka gets her campaign underway on Arthur Ashe against Dinah Pfizenmaier, while Petra Kvitova, Caroline Wozniacki and Sara Errani will also be looking for a safe passage into the second round.
