(CNN) -- French Open champion Svetlana Kuznetsova crashed to defeat in her opening Wimbledon warm-up encounter at the AEGON International in Eastbourne on Tuesday.
French Open champion Kuznetsova failed to adapt to the Eastbourne grass as she crashed out.
The Russian was playing her first match since collecting her second grand slam title at Roland Garros 10 days ago but was humbled by Canada's Aleksandra Wozniak.
Kuznetsova, the second seed, won only three games in a 6-0 6-3 defeat by the world number 23 and admitted she failed to adapt to the grasscourt.
"It's really tough for me," Kuznetsova said. "I played for two months on clay and I have it almost in my blood. On this surface, everything is opposite. For me, it's too much to change in three days."
Jelena Jankovic's miserable season continued as she also tumbled out in the first round.
The Serbian, who began the year ranked number one in the world, has largely struggled for results this season -- a minor tournament victory in Marbella apart -- and has admitted she is low on confidence.
Anna Chakvetadze, a former top-10 player who is now ranked 31, was her conqueror today, the Russian triumphing 6-7 6-3 6-2.
Third seed Jankovic mounted an impressive comeback to win the first set having been 5-1 down but could not maintain that momentum.
On a bad day for the top players, fourth seed Vera Zvonareva -- playing her first match since April because of an ankle injury -- lost 6-3 1-6 6-3 to former Wimbledon champion Amelie Mauresmo.
Reigning Eastbourne champion Agnieszka Radwanska easily disposed of younger sister Urszula in their first-round clash 6-1 6-1. It was revenge for the eighth seed, who lost their only previous WTA Tour meeting in Dubai earlier this year.
Sixth seed Caroline Wozniacki eased past Alisa Kleybanova 6-3 6-2 while former Wimbledon finalist Marion Bartoli was a 6-3 6-1 winner against Gisela Dulko.
