BASTAD, Sweden - Aravane Rezai made a winning start to her Collector Swedish Open Women campaign Monday, beating Lilia Osterloh, 64 62.

Rezai, the No.2 seed at the International-level clay court tournament, improved to 12-5 on the dirt this year with the straight set win over the American. Her most notable result of the year came on clay, winning her third and biggest Sony Ericsson WTA Tour title at Madrid, a Premier-level tournament.

Rezai was playing Osterloh for the first time. Next up for Rezai is Renata Voracova, against whom she is 1-0, beating her at an ITF event in 2007.

In something of a surprise result, No.5 seed Arantxa Parra Santonja held off Kaia Kanepi, 64 75. Though Parra Santonja was the seeded player, Kanepi was coming off a quarterfinal run at Wimbledon, and had won 26 of her last 29 matches; but perhaps she was too accustomed to English lawns, as Parra Santonja defeated her for the first time in their three Tour meetings.

Tatjana Malek, Akgul Amanmuradova and Karolina Sprem also won.

Kathrin Woerle, Nuria Llagostera Vives, Ana Vrljic and Laura Siegemund grabbed main draw berths with wins in the final round of qualifying.

The 10 remaining first round matches will take the court on Tuesday, including those of the other three Top 4 seeds, Flavia Pennetta, Lucie Safarova and Gisela Dulko, seeded No.1, No.3 and No.4, respectively.
