seeded Juergen Melzer of Austria won 11 straight games Tuesday to beat Frederico Gil of Portugal 6-3, 6-0 in the first round of the Austrian Open. Melzer, ranked at a career-high No. 26, will next play 2006 champion Agustin Calleri of Argentina in the clay-court tournament. Oscar Hernandez of Spain upset fourth-seeded Fabrice Santoro of France 6-2, 6-3, and Stefan Koubek of Austria defeated Philipp Petzschner of Germany 7-6 (8), 6-4. Juan Ignacio Chela of Argentina rallied to beat Marc Gicquel of France 5-7, 6-3, 6-0. Also, Julien Benneteau of France defeated eighth-seeded Dudi Sela of Israel 7-5, 6-1, and Ruben Ramirez Hidalgo of Spain downed Mario Ancic of Croatia 6-4, 6-3. Top-seeded Nikolay Davydenko withdrew earlier Tuesday due to a muscle injury in his left leg. Paul Capdeville of Chile replaced the 10th-ranked Russian and lost 6-3, 6-2 to Diego Junqueira of Argentina. Dokic falls In Poland, Romanian qualifier Ioana Raluca Olaru beat Jelena Dokic of Australia 6-4, 6-3 Tuesday in the first round of the Warsaw Open. The 106th-ranked Olaru broke twice in each set and only dropped serve once in the match at the clay-court tournament. “A very, very poor match – probably my worst match in the last two years,” Dokic said. “Really erratic and too many unforced errors.” Once ranked as high as No. 4 in 2002, Dokic's career stalled and four years later she tumbled to No. 617. But her resurgence peaked in January when she reached the Australian Open quarterfinals after entering as a wild card. She is currently ranked No. 72. Also, fifth-seeded Sara Errani of Italy downed Greta Arn of Hungary 6-2, 1-6, 7-6 (2), and No. 6 Daniela Hantuchova of Slovakia rallied to beat Nuria Llagoster Vives of Spain 3-6, 6-3, 6-3. “She's a very good clay-court player, and I'm really glad that I won this match because it was not easy,” Hantuchova said. Jill Craybas of the United States defeated Edina Gallovits of Romania 3-6, 7-5, 6-3, Klara Zakopalova of the Czech Republic beat Melinda Czink of Hungary, 3-6, 6-4, 6-3, and Urszula Radwanska of Poland ousted Mariya Koryttseva of Ukraine, 6-3, 3-6, 6-3. Medina Garrigues advances In Strasbourg, defending champion Anabel Medina Garrigues of Spain rallied to beat Yanina Wickmayer of Belgium 1-6, 6-3, 6-3 Tuesday in the first round at the Strasbourg International. The top-seeded Garrigues, who also won at Strasbourg in 2005 and 2007, will next face Kristina Barrois of Germany at the clay event. But four seeded players, including No.5 Tamarine Tanasugarn of Thailand and No. 6 Elena Vesnina of Russia, lost on a day of upsets. Tanasugarn lost 6-3, 6-0 to Viktoriya Kutuzova of Ukraine, and Vesnina was beaten 6-4, 6-2 by Julie Coin of France. Also, Monica Niculescu of Romania beat seventh-seeded Anna-Lena Groenefeld of Germany 4-6, 6-2, 6-3, and Alla Kudryavtseva of Russia won 6-0, 6-7 (5), 6-3 against No. 8 Nathalie Dechy of France.
