GENEVA — Thomaz Bellucci of Brazil won the revived Geneva Open title Saturday, beating sixth-seeded Joao Sousa of Portugal 7-6 (4), 6-4. The 27-year-old Bellucci's fourth career ATP title was his third in Switzerland. He also won on clay at the Swiss Open in Gstaad in 2009 and 2012. Bellucci, a 60th-ranked left-hander, wasted three set points at 5-4 in the first before winning the tiebreaker. He trailed by a service break in the second then reeled off four straight games to complete the victory. The Geneva Open returned to the ATP Tour after a 24-year gap, and replaced a tournament held in Duesseldorf, Germany. At the French Open next week, Bellucci has a first-round match against 100th-ranked Marinko Matosevic of Australia. The winner could face fifth-seeded Kei Nishikori of Japan. Thiem takes 1st career title Austrian Dominic Thiem snatched his maiden ATP career title when he beat Argentine fourth seed Leonardo Mayer 6-7(8) 7-5 7-6(2) to win the Nice Open Saturday. World No. 42 Thiem, labelled one of the world's top prospects, lacked composure in the first set as he lost the tiebreak 10-8. He took the only break of the match in the 12th game of the second set to level the tie, powering through the final set's decider 7-2. The 21-year-old Thiem is on a third-round collision course with local favourite Gael Monfils should they both progress at the French Open. Knapp wins 2nd WTA title Italy's Karin Knapp, the world No. 48, defeated her compatriot Roberta Vinci 7-6 (7/5), 4-6, 6-1 to win the WTA Nuremburg Cup and her second career title Saturday. The 27-year-old, had not tasted victory on the senior circuit since her breakthrough triumph in September 2014 at the Tashkent Open. The win comes on the eve of Roland Garros which begins in Paris on Sunday. Knapp achieved her best ever Grand Slam result in Paris last year when she reached the third round. The 2013 Fed Cup winner has been drawn against former world No. 1 Caroline Wozniacki of Denmark in the first round. Vinci, a winner of five Grand Slam doubles' titles and a teammate of Knapp during their 2013 Fed Cup victory, misses out on a chance for a 10th WTA singles' title and first since July 2013 at Palermo. Stosur claims Strasbourg Third-seeded Samantha Stosur rallied to beat Kristina Mladenovic 3-6, 6-2, 6-3 in the final of the Strasbourg International Saturday, claiming her first title of the year. The 26th-ranked Stosur, a former French Open runner-up, is returning to form after reuniting last month with former coach David Taylor. Before Strasbourg, where she won a seventh career title, Stosur had won only eight matches in 2015. The Australian dropped her serve twice in the opening set but was at her defensive best in the following sets, saving all five break points she faced. — Agencies
