In singles, Sugiyama's season started out badly, as she lost to Azarenka in Gold Coast and Gajdosova in Sydney. However, in Melbourne, her form returned, beating Vera Zvonareva (6–3, 1–1 ret.) in the first round and Tatiana Perebiynis (6–4, 6–4) in the second round, before losing to 12th seed Vaidišová (3–6, 4–6). In doubles, she and Srebotnik lost in straight sets in Sydney to Yan/Zheng, the eventual champions. In Melbourne, they drew the Williams sisters in the second round and lost 2–6, 6–7. Sugiyama's dream of a career slam died.
