It's Game, Set and Ad Match to Serena

The reigning Wimbledon champion is reportedly poised to sign a $60 million contract to market Nike sportswear for the rest of her playing career, officially making her the world's most bankable female athlete.

"It�s a big deal - in fact, it�s huge," said Brandon Steiner, the chief executive of Steiner Sports marketing agency in New York. "Serena�s greatest asset is her dominance - she�s unbeatable, she�s glamorous, she�s an immense talent.

"If you�re weighing up who�s hot, who�s the biggest person in the game, it�s Serena Williams. She�s the best thing out there."
