Nadia Petrova has produced another upset victory to reach the Australian Open quarterfinals, winning 6-3, 3-6, 6-1 against third-ranked Svetlana Kuznetsova.

French Open champion Kuznetsova committed too many unforced errors in the deciding set and was broken three times after rallying in the second to level the all-Russian match.

Kuznetsova sprayed a forehand wide to give Petrova match point Sunday and netted a service return to end it.

No. 19 Petrova had a stunning 6-0, 6-1 win over U.S. Open champion Kim Clijsters in the third round.
