STUTTGART, Germany -- New No. 1 Jelena Jankovic won her second title in two weeks, defeating Nadia Petrova of Russia 6-4, 6-3 Sunday in the final of the Porsche Grand Prix.
The 23-year-old Serb also won the China Open last week and has three titles this year.
Jankovic was assured of taking over the top ranking Monday from Serena Williams regardless of the outcome of the final. She already held the No. 1 spot for one week in August.
Williams became the No. 1 after defeating Jankovic at the U.S. Open final, but the American will drop in the rankings after losing her opening match in Stuttgart.
Jankovic won her eighth career title after overcoming a brief lapse in the second set against the 18th-ranked Russian, who won the Stuttgart tournament in 2006.
