Former champions Sam Stosur and Caroline Wozniacki cruised into the third round of the Family Circle Cup with straight-set victories today on Billie Jean King Court.

Stosur, third-seeded and the 2010 Family Circle Cup champ, took a 6-1, 6-2 win over Marina Erakovic of New Zealand. Stosur’s right calf was heavily wrapped, but she showed no ill effects from the injury that caused her to pull out of the tournament at Indian Wells last month.

Wozniacki, the No. 2 seed, took a 6-1, 6-1 win over Spain’s Silvia Soler-Espinosa. It was her sixth straight win at the Family Circle Cup, dating back to her 2011 championship.

“It was my first match of the year on clay,” Wozniacki said. “So it’s always difficult to slide and move unbelievably well. But I felt like I did pretty good out there.”

Young Americans Madison Keys and Mallory Burdette also advanced.

Burdette, 22, pulled off the biggest win of her young career, taking out 2009 FCC champ Sabine Lisicki in three sets. She won by 3-6, 7-6, 7-5 over the 15th-seeded Lisicki to set up a third-round match with world No. 1 Serena Williams.

Keys, 18, took a 6-4, 6-3 victory over countrywoman Grace Min on Althea Gibson Court, continuing what has been a breakthrough tennis season. She made the quarterfinals at a WTA Tour event earlier this year, and the third round at the Australian Open. Her ranking has leaped from No. 149 to its current No. 77, putting her eighth among American players and increasing expectations.

“I think it’s great,” she said this week. “I think if you are getting that, then obviously you are doing well. And you want to keep that, because that means you are still doing well. So, I think you kind of just have to embrace it.”
