Serbia's Jelena Jankovic moved closer to grabbing the world number one ranking from compatriot Ana Ivanovic on Thursday by beating Hungary's Melinda Czink 6-3, 6-2 at the East West Bank Classic .Jankovic reached the quarter-finals of the hardcourt event, where she will face Russia's Nadia Petrova, who eliminated fifth-seeded compatriot Vera Zvonareva 6-4, 7-5 in another third-round match Thursday.
"There's a lot to go, but I will try my best," Jankovic said. "A win is a win and hopefully I will keep getting better during the week."
Should Jankovic win Sunday's final and grab the 95,500-dollar top prize, she will overtake idle Ivanovic, last year's winner here, and reach the world number one ranking for the first time in her career.
