Fifth seed Svetlana Kuznetsova came safely through her fourth round meeting with Austrian teenager Tamira Paszek, winning 6-3, 6-2 at Wimbledon on Tuesday.
Paszek, aged 16 and competing in her first Wimbledon, had disposed of 12th seed Elena Dementieva on Monday but did little to trouble Kuznetsova.
The 2004 US Open champion displayed a range of powerful groundstrokes and was confident coming into the net, breaking the world number 54 in her first service game with a forehand volley.
A 30-minute rain break between sets did nothing to help Paszek, who was broken immediately when Kuznetsova sent a backhand down the line and again for 5-2 when she could not return a mighty forehand from the Russian.
Kuznetsova will face the winner of the match between compatriot Maria Sharapova and American Venus Williams in the last eight.
