We all know it is highly unlikely Mirza will defeat Sharapova today. Sharapova is 18, like Mirza but as far as achievments and accomplishments are concerned, there is a world of difference. Sharapova finished the year in the top 50 in 2003 (rank 32) when she was 15 and a half! Mirza ended 2003 ranked 399.
That is just the beginning of the story. Sharapova has been world number 1, she is a phenomenal player and overpowers her opponents. She has already won a Wimbledon and it would surprise many if she does not go on to win many more grand slam titles. In short, Sharapova is a tennis superstar and has the potential of becoming a legend.
Sania Mirza is a path breaker in her own right. No Indian female tennis player has been competitive at any serious professional level before. They have been stranded in the challengers. This is not related to talent in the country but the lack of infrastructure and financial restraints tennis players in the country face. The fact that there had been no past female tennis player to look upto in the country made it even more difficult for a female tennis star to come up from the country.
In 2005, Mirza, some one who has a superb win-loss record all through her career from the junior level onwards, has a 25-15. Sharapova has a 43-7. Do fans expect Mirza to beat Sharapova? Nah.
But because it is a first in Indian female tennis that a player has reached this far in a grand slam every one will be keyed up.
I have been followed tennis for 13 years from the age of 9 like it has been with most sports and have never seen any Indian reach ahead of round 2 in singles in the grand slams. Leander Paes was talented but too agressive which meant too many unforced errors. I have only heard the tales of the Krishnans and the Amritrajs. Finally there is a tennis player whom we Indian fans can call their own.
