Jarmila Gajdosova’s coach says the entire French Open field is scared of her power-packed game ahead of Saturday’s third round clash against Andrea Petkovic.

Gavin Hopper said it was time the 24th seed Australian started making bigger inroads at grand slams, starting with a victory over world No.12 Petkovic at Roland Garros.

Gajdosova showed her growing maturity by negotiating her way past crafty Spanish claycourter Anabel Medina Garrigues 7-6(4) 6-4 in cool, windy conditions in Paris on Thursday.

“She has to show that she can make that next step now and get through one of these big tournaments,” Hopper said.

“Everyone is scared of her. I am sure.

“Everyone knows she can play at a certain level and her top level is, I will go so far to say is as [high as] anyone in the world at the top level.

“But the little fluctuations in the match and it happened again today … just up and down a little bit.

“… these are good challenges for her at this moment.

“I think she is very capable of moving forward at this tournament.”

Gajdosova has never reached the quarterfinals of a grand slam, her best efforts being her fourth round appearances at Roland Garros and Wimbledon last year.

Kim Clijsters’ shock defeat on Thursday has opened up her quarter of the draw a little but it is still laced with quality players such as Maria Sharapova.

However first Gajdosova must deal with an in-form Petkovic, the German coming off the back of last week’s title win in Strasbourg.

In their most recent meeting in Brisbane four months ago, the European prevailed 6-3 6-4.

“I am looking forward to it and I will have to fight like I did today,” Gajdosova said.

Australian Open quarterfinallist Petkovic said she was bracing for the world No.26’s thumping serve and potent ground strokes.

“She has I think one of the best strokes in the world,” Petkovic said.

“She just hits so hard and serves really well.”

For anybody tuning in late to Saturday’s clash, it will be easy to spot the victor by whether or not Petkovic is pulling out some dance moves on the red dirt.

The German delighted the court 2 crowd on Thursday with a moon walk after her straight sets win over the Czech Republic’s Lucie Hradecka.

Petkovic ditched her celebration dance earlier this year but said poor results encouraged her to bust some moves again on court.

“I said I wanted to stop dancing, and it’s not a real dance anymore,” she said.

“But after I stopped, I lost two times in the second round, and I played the most horrible tennis of my life.

“So I figure I think I have to change something.

“In Strasbourg [last week], because I think it fits for clay, the moon walk, and I brought it in and I won the tournament.

“I’m here in the third round, so I think it’s going well. I have to keep it up.”
