Q.Apart from the Williams sisters and Andy Roddick, how do you feel about the current lack of top American singles players in both the men's and women's game?
Lucy Dean, England

Mike: In the women's game they've always had top American players - it's just the injuries to the Williams sisters, Lindsay Davenport and Capriati.

In the men's game I think it's just a matter of time until James Blake can win a Grand Slam. He's already in the top 10. Robby Ginepri when he gets his confidence going is one of the best players. It's just a matter of time before those guys break through in a big way.


So do you reckon those guys will 'break though in a big way'? Do you think James Blake can win a Grand Slam? Will Ginepri make top 10?
