Unconventional No. 1

On August 11, Jelena Jankovic will become the 18th player to top the rankings since 1975 , and the first one who never won a Grand Slam event. Jankovic, who has 6 career WTA titles, will replace Ana Ivanovic from the top spot, by virtue of having 8 more points than the latter.

Correction: Amelie Mauresmo and Kim Clijsters also did not win a Slam when both ascended the No. 1, Kim in 2003 (she won the US Open in 2005) and Amelie in 2004. Jankovic though, was the first No. 1 to never even reached a Grand Slam final
