Biggest dark horse in the tournament is Petrova,who has reached quarter-final spot after perfect wins over Clijsters and Kuznetsova,who were top 5 contenders for the trophy.She is playing great in Aussie Open and has big motivation to stop Henin 4 wins in a row against the Russian ..The fact that she is fresh off retirement hasn’t discouraged bookies,and they made former number 1 big favorite in this clash but now they are setting the odd like need to be..Really Henin doesn`t have her form from 2 years ago and she needs much more trainings and I didn`t see her like a favorite..She had 3 tough rounds and against Kleybanova she was break down in the 2nd set and losing 1:0 in sets but Kleybanova simply didn`t do the right thing..This is the best way to open the new season and reaching the quarter final is the best thing Henin would imagine,but I just can`t see her from being 1st semi-finalist ..Underdog to win..

4th round gives us fantastic clash between two very good players in the start of 2010..At least this will be tough match and priceless to watch..Davydenko haven`t had any good opponent to deal with but in this match he will have fantastic attacking player on opposite side..Davydenko is getting better and better..He showed that after Wimbledon and is 'unbeateable'.Davydenko is proving that he is great player with stamina like athlete and bravery like never before..His serve is just excellent and he needs to extend that in this match..Verdasco had tough match in the 1st round and had to face with left-handed home player but in the end he won in tough finish..I`m expecting excellent match to watch but also I`m expecting not an easy win for Davydenko but he is big favorite here..Also H2H is on the Russian side (6-1)..Davydenko will push Verdasco to attack and that will force Spaniard to make unforced errors..
