TOKYO — Poland's Agnieszka Radwanska beat rising star Belinda Bencic 6-2, 6-2 in the final of the Pan Pacific Open Sunday to capture her first WTA title in more than a year and return to the world's top 10 rankings. The 26-year-old Radwanska turned in a near flawless display against Bencic, smashing 28 winners past the Swiss teenager to win her second Pan Pacific Open and her first WTA title since last year's Rogers Cup in Montreal. “I'm just so, so happy I could really play my best tennis today, and this is the first tournament I've won twice, so it's definitely very special for me,” Radwanska said in her on-court interview. Bencic beat Radwanska in their only previous meeting, in the final at Eastbourne in June, and was chasing her fourth title this year. Begu stops Sasnovich In Seoul, Irina Begu halted the sensational run of qualifier Aliaksandra Sasnovich 6-3, 6-1 to win the Korea Open and lift her second WTA trophy Sunday. Belarussian Sasnovich beat Sloane Stephens and Anna Karolina Schmiedlova, the third and second seeds, on her way to the final but she could not maintain her level against Begu. The Romanian top seed, ranked 107 places higher at 29, took advantage of an error-strewn first set from Sasnovich and did not look back as she swamped the 21-year-old in the second. Lucic-Baroni defeats Stosur In China, Mirjana Lucic-Baroni of Croatia beat former US Open champion Samantha Stosur of Australia 6-2, 6-1 Sunday in the opening round of the Wuhan Open. The 85th-ranked Lucic-Baroni saved all four break points and wrapped up the match in just under an hour against her 22nd-ranked opponent. Also, American Varvara Lepchenko was a 6-4, 6-0 winner over Zheng Saisai of China. Qualifier Johanna Konta of Britain ousted 13th-seeded Andrea Petkovic of Germany in straight sets while Victoria Azarenka of Belarus, Elina Svitolina of Ukraine and Coco Vandeweghe of the United States also advanced to the second round. China's two-time Grand Slam winner Li Na earlier opened the new 15,000-seat stadium to huge cheers from her hometown fans. Similar in capacity to Wimbledon's center court, the new stadium is dwarfed only by the US Open's Arthur Ashe stadium which has a capacity of 23,000. It has a retractable roof and a metal and glass structure reminiscent of the iconic “bird's nest” stadium in Beijing, the centerpiece of the 2008 Olympics. — Agencies
