Kafelnikov Advances to Quaterfinals

Top-seed Yevgeny Kafelnikov beat David Prinosil of Germany 6-4, 7-5 Thursday at Olimpiisky Sports Complex on Thursday to reach the Kremlin Cup quarterfinals.

Russia's Kafelnikov, who has won the tennis tournament the last two years, broke Prinosil in the opening game to take the first set and then jumped to a 2-1 lead in the second set. But Prinosil, ranked No. 64 in the world, won eight consecutive points - including three aces - to stay in the match. However, in the 11th game the No. 2 ranked Kafelnikov regrouped and broke at love to close the match.

"I lost concentration for several minutes in the second set and it was enough for my opponent to break back. And it was not an easy match after that," Kafelnikov said at a news conference following the match.

He also expressed some doubts about the officiating. "All questionable calls went to my opponent. There are two or three umpires on the tour that I especially dislike. They just irritate me a lot," he said.

Kafelnikov will face his former doubles partner Daniel Vacek of the Czech Republic in the quarterfinals.

Fifth-seed Andrei Medvedev of Ukraine eliminated Russian qualifier Andrei Stoliarov 4-6, 6-4, 6-1. Stoliarov, playing his first ATP Tour event, was three games ahead in the second set before falling to the Ukrainian.

"It was difficult to play against my best friend," Stoliarov said following the match.

Two-time Kremlin Cup champion Marc Rosset of Switzerland, seeded seventh, ousted Sargis Sargsian of Armenia 6-3, 6-4. Rosset, who has played in every Kremlin Cup since the tournament began in 1990, saved four break points early in the first set before he found a way to beat Sargsian, ranked No. 57 in the world.

Rosset, 37th on the ATP Tour rankings, broke Sargsian on the fifth deuce in the sixth game with a passing backhand down the line and pleased the crowd with a high leaping overhead smash winner to close the set in the ninth game. He fired nine aces overall - one of them breaking a digit in the tournament's 10th anniversary sign behind the court.

In the quarterfinals Rosset will face Jeff Tarango of the United States.

In other action, Fabrice Santoro of France, coming off an upset Wednesday of Paris Open finalist Marat Safin on his home soil, struggled to beat Justin Gimelstob of the United States 5-7, 6-1, 7-6 (8-6). He will meet Byron Black of Zimbabwe, who played Goran Ivanisevic of Croatia to 7-6 (7-4), 3-1 before Ivanisevic retired from the match due to flu.
