Top-seeded 2004 champion Mikhail Youzhny advanced to the quarterfinals of the St. Petersburg Open, rallying to beat fellow Russian qualifier Evgeny Donskoy 3-6, 6-3, 6-2 on Thursday. In Friday's quarterfinals, Youzhny will play eighth-seeded Victor Hanescu of Romania, who advanced by beating American qualifier Rajeev Ram 7-6 (1), 3-6, 6-3. Earlier, Russian wild card Dmitry Tursunov beat fourth-seeded Yen-hsun Lu of Taiwan 6-1, 6-4 to reach his second quarterfinal of the year.
