Anna is a differnt kind of player, you can't really compare their tennis strenghts. Sharapova is 6'3 broad shoulder, she's a very, very strong girl. Anna is more comparable to Maria Kirilenko. Both Anna and Maria K were skinny girls and had to put on muscle to comppete with the bigger hard hitting girls. They have to play a game their body cannot handle. If Anna were playing in the 70's she would have been successful. Martina and Justine are small players who are champions, but we have to look at how they were raised. Martina H. was groomed from birth to be a tennis champion(she was named after one the greatest players), but even she couldn't cope with the power game and was overwelhmed. Justine is 5'5 and a 6 time champion but can still be powered off the court by the bigger girls. example, Sharpova and the US Open 2006. Another thing, Anna wasn't groomed like Maritna, Maria S, The Williams or even Jusitine. Nick Bolleteri said Anna's mom took her away from his academy too soon, and then proceeded to coach her herself. Her mom knew nothing about grooming a champion. She never let her injuries fully heal either. Lastly Anna didn't focus that much on fame. She said she only did photoshoots when she had time, she never tried to fit them into her tennis calender. Sports Illustrated editor tried for years to get her to pose and she didn't agree to do till her career was on the downslide from injuries and such.
