Su Wei Hsieh defeated Tsvetana Pironkova 7–5, 6–2 in the first round of the Australian Open on hard court, producing an upset against the pre-match favourite. Pironkova, priced at 1.30 odds, entered as the expected winner, but Hsieh's superior court performance across two sets proved decisive. The Taiwanese player controlled the opening set through to 5–5 before breaking clear to secure it 7–5, then dominated the second set to close out the match in straight sets. The result marks a significant scalp for Hsieh and raises questions about Pironkova's readiness following her extended absence from professional tennis.
