Sharapova, Radwanska, Li win French openers

Reigning champion Maria Sharapova, fourth seed Agnieszka Radwanska and former winner Li Na posted first-round victories Monday at the French Open.

The second-seeded former world No. 1 Sharapova, wearing a form-fitting optical illusion purple dress, dismantled Taiwan's Su-Wei Hsieh 6-2, 6-1 in a mere 54 minutes on Court Lenglen.

Sharapova completed a career Grand Slam by capturing Roland Garros last year, beating Sara Errani in the final.

Up next for the Russian superstar, who's a solid 31-4 this season, will be rising 19-year-old Canadian Eugenie Bouchard, a 6-1, 7-6 (7-2) victor against Bulgarian Tsvetana Pironkova on Day 2.

The 2012 Wimbledon runner-up Radwanska cruised past Shahar Peer of Israel by a 6-1, 6-1 margin in 57 minutes on the famed red clay.

Radwanska has been nursing a sore right shoulder.

"I decided to have a week of rest and just practice," she said. "I think it was a good move."

Radwanska has never advanced beyond the fourth round in Paris and was a third-round upset victim here last year.

Up next for the crafty Pole will be American Mallory Burdette.

The sixth-seeded Li, the 2011 French Open champ and this year's Australian Open runner-up, moved on with a 6-3, 6-4 win over Anabel Medina Garrigues of Spain. The Chinese star will encounter American Bethanie Mattek-Sands in the round of 64.

Meanwhile, eighth-seeded German left-hander Angelique Kerber downed German Mona Barthel 7-6 (8-6), 6-2 and 10th-seeded former world No. 1 Caroline Wozniacki of Denmark picked up her first win since early last month, ending a five-match losing streak with a 6-3, 6-2 handling of British lefty Laura Robson.

Seventeenth-seeded American Sloane Stephens moved on by besting Italian Karin Knapp 6-2, 7-5, while former French Open and U.S. Open champion Svetlana Kuznetsova ousted 22nd-seeded fellow Russian Ekaterina Makarova 6-4, 6-2. The young American Stephens, who reached the semifinals at the Australian Open in January, will face fellow countrywoman Vania King in her next outing.

Fifteenth-seeded Italian Roberta Vinci routed France's Stephanie Foretz Gacon 6-3, 6-0; 20th-seeded Spaniard Carla Suarez Navarro overcame Romanian Simona Halep 3-6, 6-2, 6-2; 21st-seeded Belgian Kirsten Flipkens fought back to beat Italian Flavia Pennetta 2-6, 6-4, 6-0; Slovak Zuzana Kucova took out 24th- seeded German Julia Goerges 7-6 (10-8), 6-0; American Melanie Oudin dismissed 28th-seeded Austrian Tamira Paszek 6-4, 6-3; and 29th-seeded American Varvara Lepchenko leveled Croat Mirjana Lucic-Baroni 6-1, 6-2.

Former champion and former runner-up Francesca Schiavone advanced with a 6-0, 7-6 (7-1) decision against Hungarian Melinda Czink. The 2010 French Open winner Schiavone is now 16-2 here over the last few years.

Several other women reached the second round, including Americans Mattek- Sands, King and Madison Keys, Serb Bojana Jovanovski, France's Mathilde Johansson, and Slovak Jana Cepelova, who bested American Christina McHale 7-6 (7-3), 2-6, 6-4.

The first round is scheduled to conclude here on Tuesday, including matches for third-seeded former world No. 1 Victoria Azarenka, seventh-seeded former Wimbledon winner Petra Kvitova and ninth-seeded former French Open runner-up and former U.S. Open champ Sam Stosur.

The Australian Open titlist and U.S. Open runner-up Azarenka will take on Russian Elena Vesnina.
