MOSCOW, Oct 11 (Reuters) Russia's Mikhail Youzhny became the latest seed to fall in the Kremlin Cup, going down to little-known German Michael Berrer 7-5 6-4 in the second round today.
The men's second seed joined a growing list of high-profile players, such as Maria Sharapova and Amelie Mauresmo, to bow out of the 2.3 million dollar indoor tournament.
Women's second seed Sharapova and sixth-seeded Mauresmo were knocked out at the first hurdle yesterday.
The 72nd-ranked Berrer broke Youzhny in the 11th game to take the opening set before repeating the trick at the start of the second to record only his second win against a top 20 opponent this year.
''I don't think I played that badly,'' world number 17 Youzhny told reporters.
''But you have to give him credit, he played really well, especially in those three games from 5-5 in the first set.'' Berrer, who has reached only his third quarter-final on the ATP Tour this year, will face eighth-seeded compatriot Philipp Kohlschreiber in the last eight.
In the first match on centre court, former world number one Serena Williams had to work harder than expected to see off Ukrainian qualifier Tatiana Perebiynis 7-5 6-4 and move into the quarter-finals.
''I don't think I've played up to my standards today but I was glad to be through,'' said the fourth-seeded American, who is making her second appearance in Moscow, 10 years after her debut.
''I was working on some things... It might not work in this match but in the future it's gonna work well for me.'' Williams, who was playing her first match after receiving a bye into the second round, said it was hard for her to get up for such an early start.
''Actually I like playing indoors on such a (fast) surface, it suits my game but I needed two cups of coffee to wake up,'' she said. ''Usually I'm still sleeping at this time (11 a.m.), so it took me a while to get going.'' REUTERS PDS BST2003
