It's time for the first Grand Slam tennis tournament of the year, the Australian Open.
Starting next Monday, Jan. 14, the best tennis players in the world will gather to take their shot at winning the tournament and stamping their place in history.
But they will be challenged, and it will not be an easy defence.
Azarenka is the top seed, but she is nursing some health problems and will probably have to conquer nemesis Serena Williams if she is to win it all again.
Williams has her own quest going, and her motivation is to see it to its completion.
Maria Sharapova and Agnieszka Radwasnka might have something to say as well before all is said and done.
Let's take a quick look at all the details on the big four and their odds in both the men and women's draw.
