ANA IVANOVIC NO. 1

Ana Ivanovic is assured of becoming the 17th woman -- and first from Serbia -- to be ranked No. 1, regardless of how she fares in the French Open final.

She will move up from No. 2 when the WTA Tour's new rankings are issued Monday, replacing Maria Sharapova in the top spot.

Ivanovic and two other women, No. 3 Jelena Jankovic and No. 4 Svetlana Kuznetsova, all had a chance to take over at No. 1 after Sharapova lost in the fourth round at Roland Garros.

But Ivanovic beat Jankovic 6-4, 3-6, 6-4 in the semifinals Thursday, while Kuznetsova lost to Dinara Safina 6-3, 6-2.

The 20-year-old Ivanovic, who will play Safina in the final Saturday, said she wasn't aware she had clinched the No. 1 ranking by beating Jankovic until after the match.
