Re: Predict who will win the 2013 head-to-head between Sharapova and Azarenka
If they have matches in Australian Open and US Open, Vika will beat Maria in 2013 as she did in 2012. It´s a pity that in the Olympics Vika´s opponent in the semifinals wasn´t either Sharapova or Kirilenko. Then we could have seen which one is better on grass.
Both of them will be top seeded players in the beginning of the season, and it requires that both of them will go deep on tournaments that will be any head to head games in the first place. If Maria Sharapova plays with a similar success as Petra Kvitova or Caroline Wozniacki did in 2012, then she won´t have many matches against Azarenka. But as in December 2012, it seems likely that the Unholy Trinity Vika-Maria-Serena will dominate the next season as well.
