Charleston, SC (Sports Network) - Former champions Caroline Wozniacki and Sam Stosur were a pair of easy second-round winners Wednesday at the Family Circle Cup tennis event.
The second-seeded Wozniacki, who only entered this tournament Saturday when a scheduled trip to Haiti with boyfriend Rory McIlroy was postponed, blew past Spaniard Silvia Soler-Espinosa 6-1, 6-1 in 59 minutes, while the third- seeded former U.S. Open titlist Stosur whipped New Zealand's Marina Erakovic 6-1, 6-2 on the green clay at Daniel Island Tennis Center.
"I felt like I really served well and returned well today," Wozniacki said after pasting Soler-Espinosa. "I'm pleased with that."
Wozniacki was the big winner here just two years ago, while Stosur was the 2010 Charleston champ.
Meanwhile, American qualifier Mallory Burdette pulled off an upset by dismissing 15th-seeded former champion Sabine Lisicki, 3-6, 7-6 (7-5), 7-5. Burdette is rewarded with a match against world No. 1 superstar and reigning Charleston champ Serena Williams.
In some other second-round action involving seeds, No. 10 Julia Goerges of Germany held off Belarusian Olga Govortsova 6-2, 0-6, 6-3 and Canadian qualifier Eugenie Bouchard upended No. 16 Brit Laura Robson 6-4, 3-6, 6-1. Bouchard will face Stosur here on Day 4.
Promising American Madison Keys eased into the round of 16 with a 6-4, 6-3 handling of qualifier compatriot Grace Min. Keys will battle another fellow American, wild card Bethanie Mattek-Sands, on Thursday.
The winner of this $795,000 tournament will earn $125,000.
