In March, Ivanovic defeated Svetlana Kuznetsova in the final of the Tier I Pacific Life Open in Indian Wells before wins over top-15 players Francesca Schiavone, Vera Zvonareva, and world No. 4 Jelena Janković, in the semifinals. She lost to Lindsay Davenport in the third round of the Sony Ericsson Open in Miami the following week in straight sets.
