Marion Bartoli withdraws at Kremlin Cup

MOSCOW -- Marion Bartoli of France withdrew from her Kremlin Cup quarterfinal with Elena Vesnina of Russia because of illness, handing Agnieszka Radwanska a spot in the season-ending WTA Championships in Istanbul.

Bartoli won her seventh career title in Osaka last weekend and needed to win the title in Moscow to secure the last open spot for next week's WTA Championships. With Bartoli's withdrawal, Radwanska qualifies for the event for the first time, despite losing in the second round in Moscow.

The third-seeded Bartoli had not dropped a set in six matches.

"I think just my whole body needed a break," Bartoli said. "I really was trying until the end, but yesterday during my match I already felt not very good.

"I still have a bit of energy left, so it was enough (to play), but early this morning I had so much pain in my whole body, on my neck -- I couldn't even warm up," she said.

Bartoli will travel to Istanbul and be the first alternate.

In other Kremlin Cup results Friday, Dominika Cibulkova of Slovakia upset top-seeded Vera Zvonareva of Russia 4-6, 6-4, 6-4 Friday to reach the semifinals.

Kaia Kanepi upset sixth-seeded Russian Svetlana Kuznetsova 6-1, 6-2 to set up a semifinal clash with Lucie Safarova of the Czech Republic, who ousted another Russian, Vera Dushevina, 6-4, 6-4.

Cibulkova, who was runner-up last week in Linz, Austria, will face Vesnina in the semifinal.

Cibulkova played with her right leg bandaged after she aggravated a knee injury in the previous match. Both players took medical timeouts in the third set -- Zvonareva to treat her shoulder and Cibulkova to have her leg massaged and retaped.

The 20th-ranked Slovak rallied from 5-3 down in the second set to break the fifth-ranked Zvonareva in the 10th game and stay in the match.

Serving in the tenth game of the third set, Zvonareva led 40-0 but could not finish. She returned wide and long to lose the game and the match.

In the men's quarterfinals, the 133rd-ranked Jeremy Chardy of France landed 11 aces to beat Philipp Kohlschreiber of Germany 6-4, 6-3. Second-seeded Viktor Troicki of Serbia defeated Alex Bogomolov Jr. of the U.S. 7-6 (6), 6-7 (1), 7-6 (1), and fourth-seeded Nikolay Davydenko of Russia downed Michael Berrer of Germany 6-3, 6-2.
