She's an Indian tennis player. Here are a few paragraphs from the same website that you posted above:
Sania Mirza is the current youth icon in India. Coming from Hyderabad, this teenager is creating history in Indian tennis by becoming the first ever Indian to break into the top-50 WTA rankings. She also became the first Indian woman to win a WTA tourney when she lifted the Hyderabad Open trophy in February 2005.
Still not out of her teens, Sania Mirza has got a huge fan following, both inside and outside the country. Having trained under C.G.Krishna Bhupathi (father of another famous Indian tennis star, Mahesh Bhupathi), Sania's ambition is to one day become one among the top-20 in the world. At the rate in which she is going currently, that day is not far off.
Sania Mirza has also been honoured with the prestigious Arjuna award by the Indian government for the year 2004.
