Juan Martin del Potro defeated Jurgen Melzer 6-2, 6-1 in Sunday's Austrian Open final to win his second straight ATP Tour event. The 19-year-old Del Potro won his maiden title in Stuttgart, Germany, last week. “These were two great weeks for me. Really unbelievable,” the Argentine player said. It was Melzer's first final of the year. The Austrian is now 1-6 in finals, winning only in Bucarest, Romania, in 2006. Del Potro became the fifth Argentine winner of the clay-court tournament in Kitzbuehel in the last six years. Sunday's final of the 63rd edition marked the end of the event, which is not included in the ATP calendar next year. Parmentier bags title In Bad Gastein, Austria, France's Pauline Parmentier won her second WTA title on Sunday, beating Czech qualifier Lucie Hradecka 6-4, 6-4 in the finals of the clay-court tournament. The 53rd-world ranked Frenchwoman followed on from her success in the semifinals where she eliminated top seed Agnes Szavay of Hungary in straight sets to lift her second title after Tashkent in 2007. The 23-year-old Hradecka, who is ranked just 232nd in the world, is more known as a doubles player and went on to win her fifth title here later on Sunday with partner Andrea Hlavackova. Tursunov stuns Blake Defending champion Dmitry Tursunov fought back from a set down to upset top seed James Blake 4-6, 6-3, 6-4 and reach the final of the Indianapolis Championships on Saturday. The Russian will now face Gilles Simon after the Frenchman reached his first career ATP final in the United States with an exciting 6-3, 4-6, 6-4 win over local favourite Sam Querrey. Blake came into the match riding the momentum from a dominant performance in the quarterfinals where he dispatched Lu Yen-hsun 6-2, 6-0. And he looked strong through the first set, where he held his serve comfortably. However, Tursunov produced a strong service set of his own, recording four aces on the way to taking the second. Tursunov broke Blake's service twice in the final set, and fended off a late charge by saving a break point in the final game. The Russian has the chance to join Americans Pete Sampras and Andy Roddick as the only players in the last three decades to defend the tournament title. In the other semifinal, Simon triumphed in sultry conditions against a tired Querrey in the first meeting between the pair. The 23-year-old Frenchman cruised through the first set with his opponent visibly struggling in the humid heat. Simon was 4-2 up in the second set and looked to have the match in the bag but, after receiving some treatment, Querrey found the energy and determination to fight back and take the set and go into a third. The advantage ebbed and flowed in the decisive set but a superb backhand from Simon at 4-4 turned the contest his way and booked him a place in Sunday's final. Wozniak-Bartoli final Marion Bartoli overpowered Japan's Ai Sugiyama 6-3, 6-3 to move into the final of the Stanford Classic on Saturday. The sixth-seeded Frenchwoman will meet Canada's Aleksandra Wozniak, who advanced when top seed Serena Williams was forced to retire with a knee injury down 6-2, 3-1. Verdasco to face Andreev Top-seeded Fernando Verdasco beat Fabio Fognini of Italy 6-1, 6-3 in less than an hour Saturday to advance to the final of the Croatia Open. Verdasco next plays fourth-seeded Igor Andreev of Russia, who beat Maximo Gonzalez of Argentina 6-2, 7-6 (2) in the other semifinal match. Verdasco dominated the seventh-seeded Fognini from the start with the Italian appearing tired after beating five-time defending champion Carlos Moya in the quarterfinals on Friday.
