Serena stays hot in Charleston opener

Fresh off her big title in Miami, reigning champion Serena Williams was an easy second-round winner Tuesday at the Family Circle Cup tennis event.

Following an opening-round bye, the world No. 1 Williams waltzed past Italian Camila Giorgi 6-2, 6-3 in 1 hour, 22 minutes on the green clay at Daniel Island Tennis Center. Williams, who swatted nine aces on Day 2, was the Charleston champ in 2008 as well as last year, when she beat Czech Lucie Safarova in the final. She was also a runner-up here in 2003.

Sloane Stephens was one of three seeded players upset in their second-round bouts, however, with the fourth-seeded 20-year-old no match for fellow American Bethanie Mattek-Sands in a 6-2, 6-0 verdict that took a mere 58 minutes to complete.

Elsewhere, Swiss Stefanie Voegele doused seventh-seeded Spaniard Carla Suarez Navarro 6-2, 6-4, while American qualifier Jessica Pegula took out eighth- seeded German Mona Barthel 7-6 (7-4), 6-1. Barthel was a titlist in Paris earlier this season.

Romanian Sorana Cirstea, the 11th seed, reached the third round via walkover when Spaniard Anabel Medina Garrigues pulled out of the draw.

Former Charleston champion Jelena Jankovic posted a 6-4, 5-7, 6-4 opening- round win against struggling American Melanie Oudin. The ninth-seeded former world No. 1 Jankovic captured this tournament back in 2007.

In other first-round action involving seeds, No. 10 Julia Goerges of Germany grounded Kazakhstan's Yulia Putintseva 6-2, 6-3; No. 12 American Varvara Lepchenko outlasted France's Mathilde Johansson 6-1, 4-6, 6-1; American qualifier Vania King upended No. 14 Yaroslava Shvedova of Kazakhstan 4-6, 6-1, 6-4; No. 15 Sabine Lisicki of Germany dismantled helpless Georgian Anna Tatishvili 6-0, 6-0 in a mere 41 minutes; and No. 16 Laura Robson of Great Britain blitzed Spaniard Estrella Cabeza Candela 6-2, 6-2. Lisicki was the Family Circle champ in 2009.

Additionally in round one, New Zealand's Marina Erakovic topped Slovak Daniela Hantuchova 7-6 (7-2), 6-4, Croat Mirjana Lucic-Baroni overcame Swiss Romina Oprandi 4-6, 6-1, 6-3, and American Madison Keys dismissed Romanian Alexandra Cadantu 7-6 (7-3), 6-4.

The winner of this $795,000 tournament will earn $125,000.
