PARIS French Open champion Ana Ivanovic officially moved up to No. 1 in the WTA Tour rankings for the first time Monday, replacing Maria Sharapova.

Ivanovic is the 17th woman, and first representing Serbia, to be No. 1.

She entered the Open at a career-high No. 2, but overtook Sharapova, who lost in the fourth round.

“Being No. 1 now holds more pressure,” Ivanovic said after beating Dinara Safina in straight sets in Saturday's final. “But you're also a professional athlete, and if you want to achieve your goals, you have to learn how to handle the pressure.”

Safina rose from No. 14 to No. 9, matching her career high.

Sharapova is now No. 2, followed by the losing semifinalists at Roland Garros, No. 3 Jelena Jankovic and No. 4 Svetlana Kuznetsova. Jankovic would have risen to No. 1 if she had beaten Ivanovic in their semifinal.

There was no change in any of the top six spots in the ATP rankings, with French Open champion Rafael Nadal staying at No.2 for the 151st consecutive week. The man he beat 6-1, 6-3, 6-0 in Sunday's championship match, Roger Federer, remains at No. 1, extending his record by sitting atop the rankings for the 228th consecutive week.

Novak Djokovic, the Australian Open champion who lost to Nadal in the French Open semifinals, is still No.3, followed by Nikolay Davydenko, David Ferrer and No. 6 Andy Roddick.

Nadal-Federer III draws lower rating

Rafael Nadal's rout of Roger Federer in the French Open final drew the lowest TV rating of the duo's three consecutive title matches in Paris.

NBC's telecast of Nadal's straight-set victory Sunday – the most lopsided Grand Slam men's final in 24 years – drew an overnight rating of 1.8, the network said Monday. It is the lowest for the French Open men's final since the 2003 championship also drew a 1.8.

That rating is down from the 2.2 rating in 2007, and the 2.1 in 2006. Each of those years, Nadal beat Federer in four sets.

NBC got a 1.8 rating for the women's final Saturday. The rating was the same in 2007, when new champion Ana Ivanovic lost to Justine Henin. AP
