Saturday proved to be a successful day for Italian women at the 2013 US Open and for none more so than Camila Giorgi.
The 21-year-old qualifier from Macerata broke through to her first round of 16 appearance at a major by defeating former world No. 1 Caroline Wozniacki in the night session on Arthur Ashe stadium.
Giorgi will be joined in the last 16 by countrywomen Flavia Pennetta and Roberta Vinci after they overcame Svetlana Kuznetsova and another Italian, Karin Knapp, respectively.
There were more upsets on Saturday as seventh seed Petra Kvitova fell to American wild card Alison Riske and 14th seed Maria Kirilenko was knocked out by the in-form Simona Halep.
Daniela Hantuchova, Ana Ivanovic and Victoria Azarenka all progressed unscathed, with Azarenka v Ivanovic looking like a cracking match-up on Monday.
In the men's draw Rafael Nadal and Roger Federer remain on course for a first-ever US Open meeting in the quarterfinals. Nadal defeated Ivan Dodig in straight sets and Federer made light work of Adrian Mannarino.
The biggest shock of the day saw No. 22 seed Philipp Kohlschreiber oust No. 13 John Isner 64 36 75 76(5). The German will be rewarded by playing Nadal in the round of 16.
There were also wins for David Ferrer, Richard Gasquet, Milos Raonic, Janko Tipsarevic and Tommy Robredo in what is looking like a good line-up.
