"It was only then that things started working for me as I began to swing a lot and played to my strength and had fun," said Sania of that break after the match. In the third set, the unseeded Sucha was broken continuously by Sania in the third, fifth, seventh and ninth games as the discerning enjoyed each and every moment of the young Indian's power play. "I've made lot of changes to my game and it has started working. I've matured as a person and as a tennis player," Sania aptly summed up her game. How much of it will translate into her winning the title here?
