Top seed Victoria Azarenka of Belarus coasted into the third round at the French Open on Wednesday with a 6-1, 6-1 win over German qualifier Dinah Pfizenmaier.
She will next play the winner of the tie between Aleksandra Wozniak of Canada and Zheng Jie of China for a place in the last 16.
It was a very different showing from the world number one compared to her first round struggle when she stared defeat in the face at a set and 4-0 down against Italy's Alberta Brianti before clawing her way back to win.
Up against a player who was making her Grand Slam debut at Roland Garros, Azarenka needed just 55 minutes to move through allowing her opponent to dig her own grave with 29 unforced errors.
Azarenka won the Australian Open in January and is seeking to become the first woman since Jennifer Capriati in 2001 to win the first two Grand Slam tournaments of the year.
