Maria Sharapova rolled over fellow Russian Nadia Petrova 6-1, 6-2 in the second round of the $7,00,000 dollar Bank of the West Classic on Wednesday.
Former World No 1 Sharapova needed just over an hour to beat current World No 10 Petrova.
Sharapova now has 13 wins and four losses in 2009 as she continued her domination over Petrova, winning seven of their eight career matches.
"I knew what I had to improve upon," Sharapova said. "I started that first match lousy. This time the goal was to get a better start."

Sharapova was playing just her 17th match since returning from a nine-month layoff because of shoulder surgery.
"I was aggressive the whole way through," she said. "I didn't have many letdowns and even when I made unforced errors I stayed with it."
