Bartoli lost 200 points in the rankings as previous tournaments' results were devalued. That dropped her to 3,540 points, just behind the 3,545 earned by Wozniacki.
That was the only change in the Top 10. There was no WTA tournament last week as the tour took a break for the first round of the Fed Cup. Two-time defending champion the Czech Republic, Italy, Russia and the Slovak Republic all advanced.
The tour returns in force this week with the Qatar Total Open pulling nine Top 10 players -- all but No. 5 Li Na who withdrew last week because of an ankle injury. No. 1-ranked Victoria Azarenka is the defending champion.
Azarenka's hold on the top ranking spot is at stake as No. 2-ranked Serena Williams needs only to reach the semifinals -- even if Azarenka repeats as champion -- to regain the No. 1 ranking. Williams was last atop the rankings Oct. 10, 2010.
Third-ranked Maria Sharapova could also return to No. 1 if she wins the tournament and Williams doesn't reach the semis and Azarenka doesn't make the finals.
Azarenka has 10,325 points and Williams is second with 9,970 with Sharapova third at 9,545.
Agnieszka Radwanska has 7,750, which is fourth most, and Li's 6,255 total has her ranked fifth. Angelique Kerber (5,400) is sixth followed by Sara Errani, who has 4,795. Petra Kvitova (4,285) is in the eight spot followed by 2012 Qatar runner-up Samantha Stosur (4,230) and Wozniacki.
There is another WTA tournament this week with the Copa Bionaire in Colombia. The event was an ITF tournament previously. Mandy Minella, No. 90 in the rankings, is the top seed.
