Tennis: Sharapova beaten

Svetlana Kuznetsova earned her first title since 2004 when she upset an unsettled Maria Sharapova 6-4, 6-3 to win the Nasdaq-100 Open tennis title in Miami.

Kuznetsova won the battle of Russians to secure her first WTA trophy since triumphing in Bali in September 2004, shortly after breaking through to claim the US Open crown.

She now owns six career titles.

Sharapova, seeded fourth, was a bundle of nerves and seemed distracted by a noisy small plane dragging an advertising banner that droned throughout the opening set until chased off by a police helicopter.

Kuznetsova will return to 10th in the rankings, sending Venus Williams down to 11th.
