Tennis experts including ex-players had predicted that Del Potro stands no chance against Federer.They were proved wrong when the Argentine outserved and outvolleyed the Swiss in their QF bout.Time and again the biased experts( Vijay Amritraj included)parrot the same lines of Federer and Murray winning the championship,and give a short shrift to Djokovic,Nadal,Del Potro and others. It is good for tennis that in any tournament one cannot predict the winner.
