Paszek stunned Russian 12th seed Elena Dementieva 3-6, 6-2, 6-3 to set up a quarterfinal clash with another Russian Svetlana Kuznetsova and guarantee the biggest pay cheque of her young career.

"I don't play for the money," said the Austrian girl with a Tanzanian-born father and Chilean-born mother.

"I'm 16. I play for the love of the game. It's so much fun for me. I have enough time to make money. I need to develop my game and keep working hard on myself. If that improves, the money will be there later on."

Paszek, the world number 54, is getting used to causing shocks.

When she won the 2006 Portoroz tournament, she became the seventh youngest champion of all time and the lowest-ranked champion at 259.

In the run-up to the Wimbledon, she pushed former champion Maria Sharapova to three sets in the Birmingham event to give Dementieva notice of her ability. Such is her potential that Larri Passos, the man who took Gustavo Kuerten to three French Opens, agreed to be her coach after being approached by Paszek's father Ariff Mohamed.

"He was one of the guys I was looking for, a coach with a big heart, big focus. We spend many hours on the court and he can push you to the limit," said Paszek who was a set down to Dementieva when play was halted on Saturday because of rain.
