TORONTO -- Top-seeded Serena Williams advanced to the Rogers Cup quarterfinals Thursday, beating 13th-seeded Kirsten Flipkens of Belgium 6-0, 6-3. Williams, coming off a tournament victory 2 1/2 weeks ago in the Swedish Open, set up a match Friday against Slovakias Magdalena Rybarikova. "She wasnt able to play her game as much as she wanted to," Williams said. "When you play such a high-ranked player, you have to go in there with the mindset of do the best you can before they can step all over you." Wimbledon champion Marion Bartoli retired because of an abdominal injury early in the second set of her match against Rybarikova. "Kind of excess of tiredness and exhaustion on my body," Bartoli said. "The pain is so large and we cant really say right now exactly (if) there is a tear at some point or if its just like a huge tightness." Rybarikova led 7-6 (5), 1-0 when the seventh-seeded Bartoli stopped playing. Playing her first event since returning from a hamstring injury that sidelined her since her major victory in London, Bartoli was in obvious discomfort as she walked to the player bench area, where she had a trainer stretch her arm and leg. "Everything that happened for me since a month (ago), its not without any tiredness," Bartoli said. "It took me so much energy to win my first Grand Slam that at some point I will have a kind of low and its normal. Im human. At the end of the day I cant be winning after winning after winning without feeling at some point a kind of exhaustion." Earlier, fourth-seeded Li Na of China fought back from a three-game deficit in the final set for a 3-6, 6-1, 7-6 (5) victory over Serbias Ana Ivanovic. Third-seeded Agnieszka Radwanska of Poland also advanced to the quarterfinals, beating American Sloane Stephens 6-1, 7-6 (2). Fifth-seeded Sara Errani of Italy beat Alize Cornet of France 7-5, 7-6 (3); and Romanias Sorana Cirstea edged Serbias Jelena Jankovic 6-3, 6-4. In late matches, sixth-seeded Petra Kvitova of the Czech Republic beat 12th-seeded Samantha Stosur of Australia 6-3, 6-3; and Slovakias Dominika Cibulkova topped 10th-seeded Roberta Vinci of Italy 6-3, 7-6 (4).

Dallas hasnt ruled out the star quarterback for Sunday nights game against Philadelphia, but all signs point to Romos back injury pushing Kyle Orton into the starting role after two years of limited play as the backup. Surely Ortons name isnt the first that comes to mind for fans wanting a change after years of damaging interceptions, fumbles or, most infamously, the field goal flub when Romo dropped the snap on a kick that could have won his first playoff game in 2006.
