Maria Sharapova certainly means business when she steps onto a tennis court.
Whatever the situation, winning or losing, there is no let-up. A big serve, blistering ground strokes, winning points often greeted with a clenched fist and shrieks of exultation.
Opponents are not so much beaten as bludgeoned into submission -- although at the handshake Sharapova is never less than courteous and sporting, the intensity replaced by a smile.
It's a winning formula that has brought the 24-year-old Russian three grand slam titles and made her the highest-paid sportswoman in the world, with an eight-year Nike deal worth a reported $70 million.
She can return to the top of the world rankings by winning Saturday's Australian Open final, capping a remarkable comeback after injuries almost ended her career.
With such a hunger for success, it's no surprise that Sharapova pays great attention to every aspect of her performance -- and that extends to her on-court appearance and apparel.
