In a sport with few certainties, there has been no constant quite like Agnieszka Radwanska's ability to capture the hearts and minds of tennis fans the world over.

Radwanska first claimed the WTA's Fan Favorite Award in 2011, and has yet to relinquish the crown in five subsequent years, a feat that impresses even the Polish sensation herself.

"I don't think it's a question for me," she told press at last year's BNP Paribas Open. "I really love my fans, too. I appreciate those awards.

"I think we really have to ask them why they're voting for me, but I just hope I can win again."

Can the former WTA World No.2 defend her title against the likes of fellow fan favorites Serena Williams, Simona Halep, and BNP Paribas WTA Finals Singapore presented by SC Global champion Caroline Wozniacki?
