12th seed Venus Williams has continued her great form at the US Open. She has defeated 5th seed Ana Ivanovic in the 4th round 6-4 6-2 in what was an impressive win.
3rd seed Jelena Jankovic took 3 sets to beat 19th seed Sybille Bammer 6-4 4-6 6-1.
Top seed Justine Henin was in devastating form as she breezed past 15th seed Dinara Safina 6-0 6-2.
"I was ready for a battle; she made a lot of mistakes, but I was very consistent," Henin said. "I was aggressive and went into the net a lot on my serves. It's good because I'll need that in my next match - hopefully my next few matches."
8th seed Serena Williams played her best tennis of the tournament as she beat 10th seed Marion Bartoli 6-3 6-4.
"I think the key was definitely being able to hold serve," said Williams, who hit 10 aces in the match. "She has a good return and was serving better today than she had at Wimbledon; I saw her play there and her serves were much faster."
