Australian Open betting on the women’s side should be very exciting with a number of the top women having a chance to win. One quarterfinal matchup has top seed Justine Henin favored in tennis betting odds against Maria Sharapova. Henin and Sharapova have nine Grand Slam titles between them, and last met in the Tour Championships final in Madrid in a match that lasted well over three hours as Henin won as the tennis betting favorite.
