Former U.S Open tennis champions Svetlana Kuznetsova and Lindsay Davenport have both been ousted in the third round.
Less than 24 hours after world number one Ana Ivanovic's shock exit, third seed and 2004 champion Kuznetsova joined the scrapheap following a 6-3 6-7 6-3 humbling by tenacious Slovenian Katarina Srebotnik.
American Davenport's defeat was less surprising as she came up against French 12th seed Marion Bartoli and went down 6-1 7-6 in a blaze of double faults.
Roger Federer, Novak Djokovic and Jelena Jankovic did not have it all their way either but lived to fight another day.
Federer struggled against Brazilian qualifier Thiago Alves, the 137th best player in the world, and gave the four-times champion the run around before Federer eventually prevailed 6-3 7-5 6-4.
