Jankovic to replace Serena in rankings

Jelena Jankovic will replace Serena Williams as the world's top-ranked player when the newest rankings are released Monday, the WTA Tour announced.
 
It will mark the second stint as the world number one for Jankovic, who also held the spot for one week in August.
 
Williams had held the top spot for the last four weeks after defeating Jankovic in the US Open final.
 
Jankovic, who has won two titles this year, made her first career final in a Grand Slam at the US Open.
 
The 23-year-old Serb also reached the semi-finals at the Australian Open and French Open, the year's first two majors.
 
Overall, Jankovic has won more matches than any other play on tour this year, compiling a 55-16 record in her first 18 tournaments.
