Petkovic, Radwanska to decide China Open

Andrea Petkovic and Agnieszka Radwanska each won in straight sets Saturday and advanced to the finals of the China Open tennis tournament in Beijing. Petkovic, seeded ninth, breezed past qualifier Monica Niculescu 6-2, 6-0 in 62 minutes in her semifinal. Petkovic won nearly three-quarters of the points on Niculescu\'s serve, getting service breaks in each of her seven receiving games. She lost just nine points in the lopsided second set. No. 11th seeded Radwanska topped Flavia Pennetta 6-2, 6-4. She also won more points (30-29) when Pennetta served than Pennetta managed and used that to finish off five of her 11 break-point chances. Radwanska is 4-0, including a pair of wins this year, in her career versus Petkovic. Radwanska, who won in Tokyo last week, will be looking for her third title of 2011 while Petkovic is going for her second. Sunday\'s winner will take home the China Open champion\'s check of $775,000 with $387,750 going to the runner-up. Niculescu and Pennetta each earned $169,447 as semifinalists.
