Maria Sharapova, struggling for form after shoulder surgery and languishing 61st in the world rankings, is refusing to be written off as a title contender at the Stanford WTA tournament. "I'm a competitor and played many tournaments and won quite a few," the three-times grand slam winner, who faces Japan's Ai Sugiyama in the first round, said. "You want to be the winner and if someone tells you otherwise they wouldn't be telling the truth." (Text courtesy: Reuters)
