The No. 2-seeded Sharapova has dropped a grand total of two games so far, including a 6-1, 6-1 victory over Ayumi Morita of Japan in a second-round match delayed a day because John Isner and Paul-Henri Mathieu didn't finish their 18-16 fifth set until after 9 p.m. on Thursday.
"Pretty long day yesterday. I feel like I warmed up, like, 20 times for this match," Sharapova said. "Yeah, it was one of those days where you just want to get on the court and then you're at the courts all day and sitting, waiting around, eating, sleeping. It's, like, a good way to put someone into retirement."
She's scheduled to be back on court Saturday in the third round against No. 28 Peng Shuai of China. The past two French Open winners will play Americans: 2011 champion Li Na of China against Christina McHale of Englewood Cliffs, N.J., and 2010 champion Francesca Schiavone of Italy against Varvara Lepchenko of Allentown, Pa.
McHale and Lepchenko might derive inspiration from 19-year-old Sloane Stephens of Coral Springs, Fla.
Stephens eliminated Mathilde Johansson of France 6-3, 6-2 Friday to reach the fourth round at a Grand Slam tournament for the first time, then rejoiced at the thought of what counts for success in this day and age.
"I'm excited," Stephens said, "because now I'm going to have more Twitter followers."
