Key matches Tuesday
•No. 2 seed Victoria Azarenka, the two-time defending Australian Open champ, faces 2008 French Open winner Ana Ivanovic. This fourth-round match was a casualty of the rain delay on Monday ... the only one of the women's fourth-rounders that was postponed. That puts the winner a day behind the other quarterinalists on her side of the draw. They are first up on Ashe.
•Top-seeded Novak Djokovic, who has gotten better as the tournament has progressed, faces Marcel Granollers of Spain. The are the match on Ashe.
•No. 5 seed Li Na of China, who has never fared all that well in New York, looks like she aims to change that this year. She will play Ekaterina Makarova, second on Ashe. The winner gets Serena or Suarez Navarro in the semifinals.
•Quietly working his way through the draw is No. 5 Tomas Berdych. He faces No. 9 Stanislas Wawrinka, last up on Armstrong.
•And 32-year-old Lleyton Hewitt, the 2011 champ, tries to keep his run going against No. 21 Mikhail Youzhny, second on Armstrong.
