I thought long and hard about this, knowing full well this selection would probably be controversial. But here is why I came to this conclusion:
She was newsworthy: Wozniacki is the top-rated female tennis player in the world. Skill is sexy, and so is relevance. I mean, Maria Sharapova is still really hot, but how relevant was she this year? Hope Solo got too much hype, Alex Morgan isn't quite there yet, Maria Kirilenko only made waves because she is dating Alex Ovechkin and Alicia Sacramone had one photo we all talked about and that was about it.
She's hot: Obviously.
We got bikini pictures from her this year: And that's always a plus.
She actually has a sense of humor: As we learned when she imitated Rafael Nadal's leg cramps—which afflicted him during a press conference and caused him to slump in his chair—at her own press conference during the US Open.
Seriously, she's hot: Just in case you missed that above.
Others receiving votes: Alana Blanchard, Lindsey Vonn, Josefine Oqvist
