Svetlana Kuznetsova lost to unseeded Kiki Bertens of the Netherlands 7-6 (6), 6-2, 7-5 in swirling wind Monday in the first round of the ASB Tennis Classic.
Kuznetsova, once ranked as high as No. 2, is a two-time Grand Slam winner. She lost to a player whose ranking climbed 120 places to 63 in 2012.
The wind on center court at the Auckland Tennis Center contributed to more than 100 unforced errors. But Bertens kept her composure in recording one of her best victories.
Kuznetsova took an extended break after dropping the second set to receive treatment for a foot injury.
Earlier, Pauline Parmentier of France ousted seventh-seeded Christina McHale of the U.S. 6-4, 6-1.
