Arina Rodionova upsets Kaia Kanepi

BIRMINGHAM, England -- Russian qualifier Arina Rodionova upset top-seeded Kaia Kanepi 6-4, 6-2 in the second round of the Aegon Classic on Tuesday.

The Estonian, who had a first-round bye, was broken once in the first set and twice in the second in her first match on grass for almost a year.

Rodionova, who had two matches in qualifying, next faces 2009 champion Magdalena Rybarikova. The 14th-seeded Slovakian beat American Coco Vandeweghe 6-2, 6-1.

"I remember last year when I played in (qualifying) here, it was much easier for me in the main draw," said Kanepi, whose No. 17 world ranking is more than 200 places higher than Rodionova's.

"I think I didn't have any rhythm at all and she played very well. I didn't move her around and it's pretty difficult to have a 'Plan B' on grass if your game's not working," she said.

Mirjana Lucic defeated the only other seeded player to lose, saving a match point in a 6-7 (2), 7-6 (4), 7-5 victory against No. 5 Roberta Vinci of Italy.

"I am very impressed and very happy that I can get a win like this," Lucic said. "Sometimes when you start the grass-court season you have to prepare your mind as well as your body. You have to stay positive, and I felt like I did that."

Lucic made the Wimbledon semifinals in 1999 as a promising 17-year-old but was absent from the WTA Tour for much of the last decade because of personal problems. After spending several years on the lower-tier ITF circuit, she is back in the top 100 for the first time since 2000.

Lucic will play either ninth-seeded Ayumi Morita of Japan or Andrea Hlavackova of the Czech Republic in the round of 16.
