If you had to make a prediction in world sport to save your life, you could do a lot worse than putting your faith in Serena Williams winning this year's Australian Open.
She is a prohibitively short priced favourite, for all sorts of reasons:
» Form: She won at Brisbane, dispatching her two biggest rivals, Belarusian Victoria Azarenka and Maria Sharapova and, like Novak Djokovic, has won 22matches in a row and four tournaments consecutively.
» Ability: At her best, there is no better female player on the planet.
» History: She has won five of her 17 Slam singles titles in Melbourne, won 11 of 15 tournaments last year and 78 of 82 matches. She is also on the revenge trail-losing in Melbourne in shock defeats last year and 2012 (to Sloane Stephens and Ekaterina Makarova respectively).
